Abstract:Abstract. Nitrile gloves are widely used in the medical and automobile field due to its superiority in hypo-allergic component and chemical resistance over natural latex gloves. However, poor elastic recovery of nitrile glove to compressive force also creates an aesthetic issue for customers with high levels of wrinkling after removing from glove box. This paper demonstrates the preliminary study on the varies chemical composition such as crosslinking agents, sulphur and zinc oxide, the accelerator agent added… Show more
“…However, all the tested samples follow the standard requirement by ASTM D6319, in which the minimum tensile strength is 14 MPa and elongation at break is 500%. 10 The interaction between rubber matrix and the ESD 086A filler is known as rubber-filler interactions. The relationship between filler content and reinforcement in filled rubbers generally follows a rule whereby as filler content increases, tensile strength gradually rises to a peak value at the optimize filler loading and subsequently declines because of the production of substantial filler aggregates.…”

Utilization of silicate minerals fillers in latex offer dual function as a compatible filler and cheapener that economical way to reduce latex consumption. This research explores the effect of using Engineered Silicate Composite Dispersion (ESD 086) as fillers for nitrile latex-supported gloves, seeking to explore their properties while ensuring cost-effectiveness. The reinforcement effect of novel Engineered Carbonate Dispersion (ECD 011) for ESD 086 filled Carboxylated Nitrile Butadiene Rubber (XNBR/ESD 086) latex films has also been explored. XNBR latex films were compounded with three variants of ESD 086 at different loadings (in phr). From three variants of ESD 086 fillers, variant ESD 086A at 10 phr shows the highest tensile strength. As the ESD 086A filler loading increased up to 15 phr, the tensile strength decreased, indicating the ineffectiveness to be used at higher loading. The work was continued by exploring the use of novel ECD 011 to minimize the decrement effect. The 15 phr ESD 086 filled XNBR latex films (XNBR/ESD 086A-15) were subjected to a hybrid loading from 0 to 1.2 phr with 0.2 phr staggered increment together with the reduction of ECD 011:ZnO ratio in the XNBR latex compounds. Results show that at 0.6:0.6 phr of ECD 011:ZnO, the tensile strength of XNBR/ESD 086A-15 latex films increased and the elongation at break also improved. Using ESD 086A can reduce the usage of XNBR latex. Still, it can only be used up to 10 phr (optimum loading) and ECD 011 can maintain the physical properties and offer maximum cost-saving options for XNBR latex glove formulation at higher loading of ESD fillers. Overall, both engineered dispersions offer potential commercial benefits for the Nitrile gloves industry.

“…3A), which are more resistant to chemicals, solvents, oils, and fats, have better mechanical properties, and less elastic nature compared to the latex ones. Generally, increasing the nitrile content increases the chemical resistance, but reduces flexibility [13]. The nitrile gloves are the most expensive of other kinds of gloves and this is the only disadvantage of them.…”
One of the lethal illnesses that humanity has ever seen is COVID-19 irrefutably. The speed of virus spread is high and happens through polluted surfaces, respiratory droplets, and bodily fluids. It was found that without an efficient vaccine or specific treatment using personal protective equipment, preventing contamination of hands, and social distancing are the best ways to stay safe during the present pandemic. In this line, polymers, nanotechnology, and additive manufacturing, or 3D printing technology have been considered to probe, sense, and treat COVID-19. All aforementioned fields showed undeniable roles during the COVID-19 pandemic, which their contributions have been reviewed here. Finally, the effect of COVID-19 on the environment, alongside its positive and negative effects has been mentioned.
