POLYBUTADIENE-BASED POWER TRANSMISSION BELTING

摘要

A power transmission belt is provided with a peroxide-cured, polybutadiene-based elastomeric composition. The elastomeric composition includes 100 parts of a rubber derived from 50 to 100 parts by weight of polybutadiene rubber; 0 to 50 parts by weight of at least one other rubber; about 1 to about 20 parts by weight per 100 parts by weight of total rubber (phr) of a type I coagent; about 1 to about 20 phr of a type II coagent; and about 0.1 to about 10 phr of a peroxide curing agent.
