Abstract

Test data covering composition cure behaviour and ageing resistance for eight samples of skim block rubber are presented. The influence of both natural fatty acid and protein content on cure behaviour is considered. The curing characteristics allow up to 20 p.p.h.r. of skim rubber to be added to normal natural rubber without addition of further curatives: a high level of vulcanisate properties is retained. For vulcanisate of comparable modulus the ageing resistance of skim is found to be superior to that of normal natural rubber grades despite the presence of up to 30 p.p.m. of copper in the skim rubber.
