What are the various types of resistant rubbers?

Weather Resistant Rubber Ethylene Propylene Rubber – These are the fastest growing elastomers because of its outstanding properties such as good weather resistant in ozone environment. It is used in tyre side walls, tank linings, wire and cables, mechanical goods, agricultural equipment and automotive applications. Modified Polyethylene or Chlorosulphonated Polyethylene – It is unique among elastomers as it is derived from a plastic. It is prepared by dissolving polyethylene in a suitable solvent and passing simultaneously Sulphur dioxide and Chlorine in the presence of a free radical catalyst to bring…

What are the General Purpose Rubbers available?

There are four types of rubbers under general purpose rubbers. They are: Styrene-Butadiene Rubber – Styrene-Butadiene Rubber (SBR) constitutes more than half of the world production of synthetic rubber and exceeds natural rubber supply. In fact, tyre industry depends more on SBR than a natural rubber because it is available in plenty and serves the purpose better after the incorporation of fillers. Butyl Rubber – Butyl rubber is produced by copolymerising small amount of isoprene (1-3%) with isobutylene catalysed by aluminium chloride (AlCl3) dissolved in methyl chloride. The extremely rapid…
