Allergy to natural rubber latex (NRL) gloves in healthcare workers is well recognized, and usually presents as immunological contact urticaria and sometimes anaphylaxis. Latex gloves can also cause allergic contact dermatitis, mostly because of rubber accelerators. As latex sensitivity is well known in healthcare settings, synthetic latex-free gloves are widely used. The most popular latexfree ...

Contaminants are easily introduced at any stage in the manufacturing process via extraneous input from the factory environment, tooling residue, off-specifi cation raw materials, and minor deviations in processing tolerances. Rapid and effective resolution of any contamination issue relies heavily on ensuring that deviations from critical specifi cations are rapidly identifi ed and the causes t...

in some special cases, rubber compounds with high amounts of unsaturated elastomer are recommended with organic sulfur donors instead of mineral sulfurs. in this condition, activated sulfur is produced in situ and curingprocess is facilitated without accelerators. organic sulfur donor compounds have low thermal stability and in the vulcanization temperature produce free and activated sulfurs. t...

In this paper the effect of a novel bifunctional additive [cyclic butylene terephthalate (CBT)] was investigated on the rheological, curing and mechanical properties of natural rubber (NR), styrene butadiene rubber (SBR), oil extended styrene butadiene rubber (oSBR), acrylonitrile butadiene rubber (NBR) and ethylene propylene diene rubber (EPDM). Results showed, that CBT acted as an effective l...

This review intends to provide an overview of historical and recent achievements in studies of microbial degradation of natural and synthetic rubber. The main scientific focus is on the key enzymes latex-clearing protein (Lcp) from the Gram-positive Streptomyces sp. strain K30 and rubber oxygenase A (RoxA) from the Gram-negative Xanthomonas sp. strain 35Y, which has been hitherto the only known...

1,3-Butadiene is a highly volatile gas that is used in the production of synthetic rubber; the major end use of the synthetic rubber is automobile tires. 1,3-Butadiene is also used for the production of high impact polystyrene and acrylonitrile-butadiene-styrene (ABS) resin plastics The predominant source of 1,3-butadiene in the atmosphere is industrial releases, which can occur during manufact...
