Expand with temperature range. Vulcanization process (Curing) is widely used in the whole rubber industry, and plays an important role in the rubber chemistry. The reaction ability of rubber molecule chain (cross link) is determined by its structure. Unsaturated diene rubber (such as natural rubber, styrene butadiene rubber and nitrile rubber) molecular chain containing unsaturated double bond, with sulfur, phenolic resin and other organic peroxides by substitution or addition reaction to form intermolecular cross-linking. Saturated rubber is generally used with a certain energy of free radicals (such as organic peroxide) and high energy radiation and so on. Containing functional groups of rubber (such as chlorosulfonated polyethylene), by specific reactions of various functional groups and established material and formation of crosslinks in the as and metal oxide, amine reaction and crosslinked by rubber sulfenamide based.
