Abstract:

The demand for rubber gloves has significantly increased in both medical and non-medical fields due to the spread of the coronavirus in 2019. It is challenging for rubber glove manufacturing industries to balance the production and demand for the product. Additionally, they must determine techniques to decrease the production costs so as to make rubber gloves more economical for consumers. Generally, natural gas, fossil fuels, and renewable energy sources are used worldwide in the manufacturing of rubber gloves. In addition, Thailand uses biomass energy for rubber glove production, but biomass utilization is not economically friendly. This study used different biomasses as fuel in rubber glove production so as to reduce production costs and make the process more environmentally friendly. Wood chip (WC), palm kernel shells (PKS), and oil palm mesocarp fiber (OPMF) biomass were collected from local regions and used in different ratios. The samples of WC, PKS, and OPMF were prepared in four different ratios, namely, 88:12:0, 85:15:0, 85:13:2, and 85:10:5, for efficient biomass utilization. The 85:10:5 (WC: PKS: OPMF) ratio was found to be the optimal ratio as the annual production costs of rubber gloves significantly decreased to USD 1.64 per 1000 units of gloves. Furthermore, this biomass ratio also showed the best boiler efficiency of 74.87%. Therefore, WC, PKS, and OPMF biomass are recommended as fuel for rubber glove industries to make sustainable and economical production processes.

Abstract:

The focus of this research was to investigate how grip strength and forearm muscle force were affected by two types of gloves, rubber and leather. Grip strength was significantly less in the two gloved conditions than in a barehanded condition. However, EMG analysis of muscle activity revealed no significant difference in muscle activity across the gloved and barehanded conditions, indicating that subjects generated maximal exertions in all conditions. Therefore, a certain amount of muscle force is lost in the hand-glove interface while producing maximal grip forces in the gloved conditions. Internal muscle force measurement could thus be used to aid in glove selection for submaximal tasks in industry.

Abstract:

Natural rubber (NR) gloves manufactured from NR latex are widely utilized in various applications as a personal protective device due to their exceptional barrier characteristics in infection control. However, the use of NR gloves was associated with concerns about an NR protein allergy. With comprehensive leaching procedures now a common practice in NR latex glove factories to eliminate latent rubber proteins and chemical allergens, occurrences and complaints of protein allergy from medical glove users have decreased drastically over the past two decades. The present work aims to eliminate further the residual rubber allergens in NR latex through effective purification of the NR latex and compounding the thus purified latex with an established formulation for allergy-free NR for glove applications. NR latex was purified by deproteinization and saponification, respectively. Several analytical techniques were used to verify rubber allergens eliminated in the purified latexes. Saponified NR (SPNR) latex was the purified NR latex of choice since it is devoid of allergenic proteins and poses the lowest risk of Type I allergy. The purified NR latex was compounded with zinc diethyldithiocarbamate (ZDEC), zinc dibutyldithiocarbamate (ZDBC), and zinc 2-mercaptobenzothiazole (ZMBT), respectively, for glove dipping. Among the investigated accelerators, only ZDBC was not detected in the artificial sweat that came into contact with the dipped articles. Thus, it is deduced that ZDBC poses the lowest risk of Type IV allergy to consumers. Additionally, the morphological and physical properties of dipped articles were assessed. It was revealed that the dipped film from the SPNR latex compounded with ZDBC provided thinner and less yellow products with a more uniform internal structure and a tensile strength comparable to those of commercial NR gloves.

Abstract:

Glove tear or perforation is a common occurrence during various activities that require gloves to be worn, posing a significant risk to the wearer and possibly others. This is vitally important in a clinical environment and particularly during surgical procedures. When a glove perforation occurs (and is noticed), the glove must be replaced as soon as possible; however, it is not always noticeable. The present article is focused on the design and development of a novel fluorescence-based sensing mechanism, which is integrated within the glove topology, to help alert the wearer of a perforation in situ. We hypothesized that natural rubber gloves with curcumin infused would yield fluorescence when the glove is damaged, particularly when torn or punctured. The glove design is based on double-dipping between Natural Rubber Latex (NRL) and an inner layer of latex mixed with curcumin, which results in a notable bright yellow-green emission when exposed to UV light. Curcumin (Cur) is a phenolic chemical found primarily in turmeric that fluoresces yellowish-green at 525 nm. The tear region on the glove will glow, indicating the presence of a Cur coating/dipping layer beneath. NRL film is modified by dipping it in a Cur dispersion solution mixed with NRL for the second dipping layer. Using Cur as a filler in NRL also has the distinct advantage of allowing the glove to be made stronger by evenly distributing it throughout the rubber phase. Herein, the optimized design is fully characterized, including physicochemical (fluorescence emission) and mechanical (tensile and tear tests) properties, highlighting the clear potential of this novel and low-cost approach for in situ torn glove detection.

Abstract:

Malaysia is the largest producer and exporter of examination and surgical gloves in the world and currently faced with mitigating large amounts of waste generated during the glove production process. This waste is mainly generated from glove dipping tanks and is referred as dipping tank coagulum (DTC). It is considered as scheduled waste which requires mandatory disposal by incineration, in compliance to the Scheduled Waste Regulations set by the Department of Environment. Work described in this study showed, DTC samples with a polymer content of >40%, both ash and calcium carbonate content of <10% and curatives <2% (Sulphur, antioxidants, accelerators and ZnO) when blended with virgin rubbers (SMR 10 and SMR 20) were found to be suitable for manufacturing value-added rubber products. DTC samples with polymer contents of <40% and lower in curativescould still be considered for recycling, by adding higher portions of virgin rubber for manufacturing products like shoe soles, carpet underlay and thermoplastic elastomer products. Glove manufactures should ideally set up on-site DTC processing facilities at their factory premises equipped with crepers as well as space to ‘air dry’ the creped DTC samples. Creped samples could be sent to the Malaysian Rubber Board (MRB) for chemical analyses. Factory owners could also present the analytical results from MRB to the recyclers to obtain a good premium for their processed DTC samples to be used as raw materials.

Abstract:

The glove formers are tools used to pick up the coagulants and rubber latex, so the vulcanised rubber takes the form of hands upon drying. As the demands of gloves quality is crucial to serve the purpose of gloves as a bidirectional protective barrier; the gloves are required to be both sturdy and strong as to prevent tearing while also being elastic and comfortable to use. This research is a comparison study on the surface treatment of a ceramic glove former and how it affects the contact angle between the former surface and the coagulant, and the latex being deposited on the former. The study also focuses on the mechanical properties of the gloves and defects produced by the formers. Gloves were made using the two types of formers and the gloves were then tested for their masses, thickness distributions, tensile strengths, elongations and defects. It was found that the talc treated formers was able to adhere coagulant better, a lower contact angle of 22.10 as compared to the untreated former which had a contact angle of 27.60. This enabled the talc treated former to produce natural rubber gloves which had higher mass and more evenly distributed.

Abstract:

Both synthetic and natural rubber latex can be used to form rubber latex glove films for medical and dental applications. The objective in this research is to study the natural and synthetic rubber latex glove films formation by dipping process with the bone china ceramic hand molds for 5, 10, and 15 min. From the experimental, the obtained natural rubber latex glove films are good appearance and good physical-mechanical properties i.e. smooth film surface, light pale yellow color, soft, translucent, high tensile strength, high elongation at break, and high flexibility better than those of synthetic rubber latex glove films. When the dipping time of bone china hand mold into natural rubber latex compound increases effect to tensile strength, thickness, and elongation at break increase. Tensile strength, elongation at break, and tensile stress of natural rubber latex films dipped for 15 min are equal to 12.82 ± 1.19 MPa, 1090.91 ± 4.92%, and 39.23 ± 3.63 N, respectively.

Abstract:

This study was conducted to determine changes in overall costs associated with conversion to powder-free gloves including cost of workers' compensation cases for natural rubber latex (NRL)-related symptoms and health care workers' glove satisfaction. The study, a 2–year, longitudinal design with retrospective and prospective aspects, was developed to determine health care worker use of powder-free, low-protein NRL gloves, sensitization, cost, and glove satisfaction. Informed consent was obtained from 103 health care workers. Prior to glove conversion, nearly one-half (44%, 36 of 82) of the operating room staff reported symptoms related to NRL exposure. At the end of the 14–month data collection period, only 27% (22 of 82, McNemar test = .007) reported symptoms related to NRL exposure. Additionally, a cost savings of $10,000 per year for gloves was evident with reports of increased user satisfaction. This study demonstrated that conversion to the use of powder-free, low-protein NRL gloves not only reduces health care worker NRL symptoms, but also positively affects the costs of glove purchases and workers' compensation.

Abstract:

Abstract The frictional properties of rubber surfaces modified by various treatments have been investigated in order to understand the factors which reduce the friction and give the surface appropriate qualities for practical use. The study was in two stages. Initial measurements were made on thin sheets of hot-vulcanized natural rubber; then followed tests on latex glove material to see how the initial results and understanding related to the application. Measurements of friction coefficient were made against a wavy glass plate, giving reproducible results, and against finger skin. Supplementary measurements were made of surface roughness and hardness, liquid contact angle, and water absorption. Factors of importance in the reduction of dry friction were found to be an increased surface roughness and hardness. In practice, difficulties may be experienced under slightly wet or damp conditions, which can increase the friction above the dry value. Here it was found to help if the surface treatment could absorb water. For surgeons' gloves in contact with moist skin, one particular treatment, a hydrogel polymer coating, gave the necessary surface roughness, hardness, and water absorptivity, making the gloves easy to don and pleasant to wear.

Abstract:

Waste rubber is an environmental concern. The large global market of concrete products could usefully consume this waste, even if the fractions used were very low, provided such concrete mix had sufficient strength and other characteristics. Therefore, the properties of concrete mixes that include natural rubber were studied at 28 days of age, which is a standard time to characterize hardened concrete properties. We included two types of natural rubber in this study, namely natural rubber latex (NRL) and discarded rubber glove. First, 60% concentrate latex (HA: high ammonia) was used in latex per cement ratio 0.10 by volume. Second, discarded rubber gloves, passed through a #6 sieve with 3.36 mm size, were used to investigate effects of soft rubber particles, on strength and insulation properties of lightweight concrete. The hybrid rubberized concrete mixes had 0%, 10%, 20% and 40% partial substitution of sand by volume, at water-cement ratio of 0.45 by volume. Density, compressive strength, flexural strength, insulation property, and coefficient of thermal conductivity were measured. A small 10% fraction of rubber particles improved flexural strength. However, compressive strength decreased with the amount of rubber in concrete. The thermal conductivity was slightly lower than that of normal concrete. Natural rubber addition can produce a moderately lightweight concrete, with good thermal insulation, and the inclusion of rubber glove waste in concrete aggregate appears feasible. Applications could also include non-primary structural uses with medium to low strength requirements, benefiting from other features of concrete. The results suggest that waste rubber can be used to create value-added concrete composites with sufficient structural strength, and improved thermal insulation.

Abstract:

Abstract The release of zinc dialkyldithiocarbamates from a batch of surgical gloves into the sweat of human subjects was studied. Healthy volunteers from both sexes were asked to don the gloves on both hands for 1 h. The identification and estimation of dithiocarbamate residues released into the sweat were carried out using thin layer chromatography (TLC) and high performance liquid chromatography (HPLC). The thin layer chromatogram showed that zinc diethyldithiocarbamate (ZDEC) accelerator residues were released into the sweat of volunteers. The estimation by high performance liquid chromatography revealed that the amount of ZDEC released varied among the human subjects despite using the same brand of glove. The effect of sweat rate and pH on the amount of ZDEC released into hand sweat was investigated. The results indicated that it may not be possible to derive a relationship between the sweat-extractable ZDEC and sweat rate or pH of hand sweat. The dithiocarbamate release was studied in the laboratory using a physiologically simulated medium, namely, artificial sweat at different pH levels. The glove was filled with artificial sweat and extracted for 1 h at 37 °C. It was found that amount of artificial sweat-extractable ZDEC varied with changes in pH of artificial sweat. Lack of a clear relationship between the sweat-extractable ZDEC and sweat rate or pH of hand sweat indicated that factors such as hand exercise, glove-fit, etc., may also be considered when simulating actual use conditions in vitro.

Abstract:

On eight occasions, five volunteers each handled five pieces of meat with bare hands or while wearing dry or wet knitted gloves or rubber gloves after hands had been inoculated with Escherichia coli or after handling a piece of meat inoculated with E. coli. On each occasion, after all meat was handled, each piece of meat, glove, and hand were sampled to recover E. coli. When hands were inoculated, E. coli was recovered from all meat handled with bare hands, in lesser numbers from some pieces handled with knitted gloves, and from only one piece handled with rubber gloves. When pieces of inoculated meat were handled, the numbers of E. coli transferred to uninoculated meat from bare hands or rubber gloves decreased substantially with each successive piece of uninoculated meat, but decreases were small with knitted gloves. The findings indicate that, compared with bare hands, the use of knitted gloves could reduce the transfer of bacteria from hands to meat but could increase the transfer of bacteria between meat pieces, whereas the use of rubber gloves could largely prevent the first and greatly reduce the second type of bacteria transfer.

Abstract:

Disposal medical gloves are an important product to maintain hygienic conditions, ensuring security for patients and safeguarding against infections. They are used in many fields, such as dental and medical, beauty and cuisine, food and pharmaceutical industries. Presently, aging populations and an emerging middle class in developing countries require medical gloves at a higher volume. Therefore, the demand for medical gloves increases continuously. In this work, two types of hand molds were prepared from stoneware clay and plaster to be used in the natural rubber glove preparation. The ceramic stoneware and plaster hand molds were prepared by the slip casting. The obtained stoneware hand molds were found to be superior to the commercial hand molds. Natural rubber latex (NRL) gloves were fabricated by dipping the stoneware hand mold coated with a coagulant into the NRL compound using the sulfur curing system at 120°C for 30 min. The latex solid:water weight ratio, drying and firing temperatures, and firing time used to prepare stoneware hand molds were found to affect the adsorption–adhesion properties between the mold surface and the NRL films. The obtained NRL films were further characterized for the physical properties such as appearance, film thickness, tackiness, and effusion of the phase formation by X-ray diffraction, the microstructure by scanning electron microscope, and the mechanical properties. The NRL glove films prepared by the stoneware hand mold possessed the high percentage elongation at break and the maximum load stress equal to 1343.30 ± 78.36% and 12.74 ± 2.34 MPa, respectively. On the other hand, the latex glove films prepared by the plaster hand mold with 80 consistency provided the percentage of elongation at break and the maximum load stress equal to 531.76 ± 2.54 and 21.01 ± 0.08 MPa, respectively.

Abstract:

Mangosteen peel powder is one of the most important bio-antioxidants. Adding mangosteen peel powder as filler into natural rubber latex compound for latex glove film formation via dipping process can help the green anti-microbial properties. The physical (smoothness and thickness of film) and mechanical properties (tensile strength and elongation at break) of latex film are still good. Therefore, adding mangosteen peel powder into natural rubber latex gloves can reduce the anti-allergic and antimicrobial on the film surface. Mangosteen peel powder ground by rapid mill is fine particle and high surface area 2.4216 m2/g suitable for homogeneous and compatible for adding into natural rubber latex compound. Ceramic hand mold was dipped into the Ca (NO3)2 coagulant only 3 seconds, then dipped into the natural rubber latex compounds added mangosteen peel powder for 15 seconds, withdrawn hand mold slowly, cured in the oven at 120°C for 30 min, then dried at room temperature, and casted it off the hand mold. The obtained natural latex glove films added mangosteen peel powder are smooth, clear, and thin film surface, the highest elongation at break 803.2711 ± 31.6477%, good tensile strength 30.2933 ± 6.0218 MPa, dense film without water leakage, and good contact angle.

Abstract:

The demand of the rubber glove had increased significantly since early of the year 2020 due to the COVID-19 virus breakout especially in the medical and healthcare sector. Rubber Glove Manufacturing Residue (RGMR) is the by-product from the effluent treatment by coagulation process in the manufacturing procedure. Non-recyclable RGMR are disposed to landfill after treated. This research is aimed to reuse the RGMR in cemented interlocking bricks to address the natural resources depletion issues and greenhouse gases released from the burnt brick production. The comparison in terms of physical and mechanical properties was conducted in between RGMR and crumb rubber interlocking bricks (RIB). RGMR and crumb rubber were used as partial fine aggregate replacement by 10% while fly ash was used as a cement replacement material by 56%. Four mixes were tested, and the interlocking bricks were categorized as medium weight bricks. However, only control mix and RGMR-2 mix fulfilled the loadbearing masonry requirement of a minimum of 13.8 MPa. RGMR-2 utilizing 10% fine aggregate replacement using RGMR without cement replacement. As for the mixes utilizing fly ash and fine aggregate replacement, RGMR-1 mix and RIB mix show compressive strength of 12.15 MPa and 11.64 MPa respectively. Besides that, the use of RGMR reduced the water absorption compared to RIB mix due to the larger particle size of crumb rubber. The water absorption rate for RIB mix has exceeded the limit of water absorption for the medium weight bricks of 240 kg/m3. The finding indicates that the RGMR exhibited a better performance as compared to the crumb rubber.

Abstract:

Wearable devices such as data gloves have experienced tremendous growth over the past two decades. It is vital to develop flexible sensors with fast response, high sensitivity and high stability for intelligent data gloves. Therefore, a tractable low-cost flexible data glove with self-calibration function based on a space-division multiplexed flexible optical fiber sensor is proposed. A simple, stable and economical method was used to fabricate flexible silicone rubber fiber for a stretchable double-layered coaxial cylinder. The test results show that the fiber is not sensitive to the temperature range of (20~50 °C) and exhibits excellent flexibility and high stability under tensile, bending and torsional deformation. In addition, the signal detection part of the data glove enables compact and efficient real-time information acquisition and processing. Combined with a self-calibration function that can improve the accuracy of data acquisition, the data glove can be self-adaptive according to different hand sizes and bending habits. In a gesture capture test, it can accurately recognize and capture each gesture, and guide the manipulator to make the same action. The low-cost, fast-responding and structurally robust data glove has potential applications in areas such as sign language recognition, telemedicine and human–robot interaction.

Abstract:

Existing natural latex radiation-attenuating gloves (RAGs) contain a high loading of radiation attenuation filler that reduces their mechanical properties to below Food and Drug Administration (FDA) medical glove requirements. RAGs are commonly formulated using Hevea natural rubber latex and lead-based fillers. The former can cause life-threatening allergic responses and the latter are known for their toxicity. In this work, a new lead-free RAG formulation based on circumallergenic guayule natural rubber latex (GNRL) and non-toxic radiation attenuation filler bismuth trioxide (Bi2O3) was developed. GNRL films with Bi2O3 loadings ranging from 0 to 300 PHR at different thicknesses were prepared. Radiation attenuation efficiencies (AE) at 60, 80, 100, and 120 kVp were determined and attenuation isocontour curves predicted film thickness and Bi2O3 loading required to meet or exceed the radiation attenuation requirements of ASTM D7866 and commercial RAGs. Optimal curing conditions for GNRL/Bi2O3 films with 150 PHR Bi2O3 were investigated by varying curing temperatures and time from 87 °C to 96 °C and 65 min to 90 min, respectively. In general, as the loading of the filler increased, the density of the films increased while the thickness decreased. GNRL/Bi2O3 films with 150 PHR Bi2O3 and 0.27 mm provided 5% more AE than RAG market average attenuation at the same thickness. The films with 150 PHR Bi2O3 cured under near-optimal conditions (90 °C/85 min, and 87 °C/65 min) met both the radiation attenuation standard (ASTM D7866) and the natural latex surgeon and examination glove standards (ASTM D3577 and D3578, respectively). Thus, gloves made using our formulations and protocols demonstrated potential to meet and surpass medical natural latex glove standards, offer a single product for both infection control and radiation protection instead of double-gloving, provide a greater degree of comfort to the user, and simultaneously reduce contact reactions and eliminate potential latex allergic reaction.

Abstract:

In this study, HP/ENR blends were prepared in aqueous solution with different hydrophilic polymers for rubber glove donning coating application. HP/ENR blend films were prepared using cast films technique to investigate the film formation prior to coating onto rubber glove. The films surface morphology were characterised using Scanning Electron Microscopy (SEM) and Light Microscopy (LM). While, the thermal properties of the films were determined using Differential Scanning Calorimetry (DSC). The microscopy results showed that coherence film formation can be obtained even though the PVA/ENR and PAA/ENR blends were immiscible. DSC result showed that the glass transition temperature (Tg) of the blends shifted to higher temperature compared with Tgof ENR. The preliminary evaluation of coating onto rubber latex film indicated that PVP/ENR blend is feasible as coating material.

Abstract:

ABSTRACT Raw hen eggshell powder, a calcium carbonate source, was used as a biofiller in the natural rubber latex compound and latex glove film formation via dipping process. The powder was anticipated to improve the physical (smoothness and thickness of film) and mechanical properties (tensile strength and elongation at break) of latex film and to reduce the extractable protein content on film surface. Eggshell powder ground by a rapid mill was fine particles of approximately 37.48 μm in diameter, suitable for homogeneous and compatible addition into the natural rubber latex compound. Dipping hand mold into the natural rubber latex compound with 50 wt% eggshell added was the best formula to obtain a smooth, clear, thin film surface, with the tensile strength of 23.24 ± 0.745 MPa and the highest elongation at break of 723.99 ± 14.60%, along with a low protein content, a dense film without water leakage, and with a good contact angle. The natural rubber latex glove film possessed good physical-mechanical properties and a low protein content as the results of the raw eggshell powder added as a biofiller.

Abstract:

The handling of vinyl polysiloxane (addition silicone) impression putties with latex gloves is said to interfere with the setting of these impression materials. The aim of this study is to evaluate the effect of handling techniques on the setting of vinyl polysiloxane impression putties using several types of gloves. The setting of these materials was evaluated by means of an elasticimeter. Four vinyl polysiloxane putty impression materials and five brands of gloves (one made of vinyl, one of synthetic rubber, and three of natural rubber) were studied. Based on the type of glove, they were previously washed or not, and a spatula was used or not for initial mixing (before handmixing). The vinyl, the synthetic and one of the natural rubber gloves did not require the previous washing procedure and/or the use of a spatula for initial mixing. Two other natural rubber gloves - depending on the silicone -, showed satisfactory results only when the initial mixing was performed with a spatula. It was concluded that setting inhibition depends on the kind of vinyl polysiloxane impression material and the kind of gloves used, but when the initial mixing was performed with the spatula this setting inhibition was overcome. The results of this study also showed that it is possible to associate cross-contamination control and satisfactory performance of addition silicone putty materials. When doubts arise from the compatibility between vinyl polysiloxane impression putties and gloves, the initial mixing should be performed with a spatula.

Abstract:

The effects of different particle sizes of recycled nitrile glove (rNBRg) on curing characteristics and physical properties of natural rubber/styrene butadiene rubber/recycled nitrile glove (NR/SBR/rNBRg) blends were investigated. The particle sizes of rNBRg were differentiated by the method of sizing. S1 was obtained by cutting the rNBRg into smaller sheets; S2 was obtained by passing rNBRg through 2 rolls mill for 10 times; and S3 was obtained by passing rNBRg through 2 rolls mill for 10 times and then mechanically grinded. NR/SBR/rNBRg blends were prepared at 50/30/20 composition using two roll mill at room temperature, with different particle sizes, rNBRg (S1), rNBRg (S2) and rNBRg (S3). Curing characteristics (scorch time, cure time, minimum torque and maximum torque), tensile properties and physical properties (crosslink density, resilience and hardness) of the blends were investigated. Results indicated that scorch time, cure time and minimum torque decreased as the rNBRg particle size decreased, while maximum torque and crosslink density increased. Tensile strength of the blends decreased as the rNBRg particle size reduced, which explained the formation of holes on the surfaces of tensile fracture, observed by scanning electron microscope. The rigidity of NR/SBR/rNBRg blends increased when smaller rNBRg particles were used, which explained the increased in hardness and decreased in resilience of the blends.

Abstract:

AbstractAs many chemicals, also agricultural pesticides (APs) can be hazardous if not used safely. Under typical working conditions, the majority of exposure to the APs is through the hand-skin. Wearing appropriate gloves should be a standard practice when handling the APs. Unlike professionals, amateurs applying the APs in their gardens or vineyards are not trained for the workplace hygiene. In this survey conducted in the spring 2015 across the Slovak Republic, practices regarding the use of protective gloves were obtained. 520 copies of the “paper-and-pencil” questionnaire were distributed to amateur users and specialized stores selling the APs (return rate of 59 %). A set of ten questions a “closed-ended” or “multiple-choice” type was offered. 75 % of respondents wear gloves when handling the APs. Regrettably, among users wearing gloves, 58 % use the same disposable gloves repeatedly, 67 % wear the reusable gloves from last season, and 53 % do not wash outside of the reusable gloves with detergent before removing them. 30 % of glove users wear all available gloves including absolutely inappropriate materials like fabric and leather, 28 % do not recognize the glove material which they use, 20 % use disposable Latex and 3 % Vinyl and Polyethylene gloves. Only 19 % of glove users wear a material that is generally considered a good choice for handling the APs (7 % Neoprene & Latex, 5 % Neoprene, 5 % Nitrile, and 2 % Butyl rubber). The survey showed the need for better education about adequate protective gloves not only for amateur users but also for retailers selling the APs and protective equipment.

Abstract:

Waste pre-vulcanized nitrile latex (WPNL), obtained from nitrile glove dipping tank was blended at different ratios with concentrated ENR latex processed via ultrafiltration and designated as ENRLC-SP20 and ENRLC-SP50, respectively, with the number indicating, the percentage of WPNL incorporated into the blend. The blends were prepared in the latex stage and subsequently processed into dry rubber. The rubbers were then blended with virgin nitrile rubber (NBR) at various ratios and the curing characteristics and physical properties of the blends were evaluated. The results showed the maximum torque (MH) decreases while the minimum torque (ML) increases with increasing level of SP 50 rubber. Using higher concentrations of SP-50, the results showed slight reductions in the cure (t90) and scorch time (ts2), respectively. It was also found that by increasing ratio of ENRLC-SP20 and ENRLC-SP50 improves the heat ageing resistance of NBR blends at 100°C as evidenced by the higher percentages in retention of the blends, compared to the control compound.
