Abstract

Chloroprene rubber (CR) is synthetic rubber widely used for seal, joint, and also adhesive. For making rubber good, additives are needed and it can influence the properties of vulcanizate. Phenolic resin is used as additives in this study. This study aims to determine the curing characteristics and mechanical properties of chloroprene vulcanizate. The chloroprene vulcanizates were done by two-roll mill by adding phenolic resin. The phenolic resins were varies i.e: 0, 10, 20, and 30 phr. The curing characteristics of the CR vulcanizates were studied by rheometer at 140 ºC, 150 ºC, and 160 ºC. The phenolic resin improves the mooney viscosity, scorch time and optimum curing time. The compound without phenolic resin gives the highest mooney viscosity and optimum curing time. The 10 phr phenolic resin give the best mooney viscosity, optimum curing time, constant rate, activation energy and also tear strength. The suitable curing temperature for CR compound is at 150 ºC and the 10 phr phenolic resin is the proper additive for CR vulcanizate.
