Abstract

A vulcanizable elastomer compound is processed and extruded by mixing the ingredients e.g. synthetic rubber reinforcing pigments, plasticizers, vulcanizers, and antioxidants to partly plasticize the compound, either forming the mixture into slabs for future use or feeding the mixture directly to a mill to plasticize the compound further, feeding the plasticized compound and up to 100 per cent by weight of scrap stock to a strainer, feeding the mixture to a blending mill, then a feed mill, and finally extruding the mixture to form tyre parts. The synthetic rubber may be formed by the copolymerization of butadiene and styrene or butadiene and isoprene with small amounts of isobutylene.
