Rubber composition containing sulfur curative and pentaerythritol ester of carboxylic acid

摘要

A rubber composition is disclosed comprising, based on parts by weight per 100 parts by weight rubber (phr): at least one diene based elastomer comprising at least one of natural cis 1,4-polyisoprene rubber and synthetic rubber derived from one or more diene hydrocarbon monomers, and mixtures thereof; 0.1 to 10 phr, alternatively 2 to 8 phr, of sulfur comprising at least one of insoluble and soluble sulfur, and 0.5 to 10 phr, alternatively 0.5 to 3 phr, of pentaerythritol ester of carboxylic acid. The rubber composition may be used in a tire or for embedding a wire such as a brass coated steel wire in it.
