RAW MATERIALS AND COMPUNDS IN RUBBER INDUSTRY
Ethylene-propylene-diene rubber (EPDM) and its saturated counterpart EPM are very durable rubbers. EPM can only be vulcanized with peroxides as it is fully saturated. EPDM has an unsaturation in the side chain giving it a very good aging resistance. Butyl rubber (IIR) is a specialty rubber that is used in inner tubes because of its low gas

Vulcanizates of EPDM and diene rubber blends - The B. F
Polymer blends of ethylene-higher α-olefin-polyene (EPDM) polymers with highly unsaturated diene rubbers are cured using sulfur and a N,N-(higher alkyl) thiocarbamylsulfenamide as a vulcanization accelerator. The vulcanizates exhibit improved tensile strength, flex-heat build-up, and oil swell properties.

Diene polymers
Because these diene polymers have double bonds in the backbone chains after the polymer is formed, they can be crosslinked by a process called vulcanization. This is done by heating the polymer with sulfur. The sulfur reacts with the two carbon-carbon double
