EPDM denotes a terpolymer based on three monomers: ethylene, propylene and a non-conjugated diene; EPDM grades have a residual unsaturation in the side chains and can therefore be cured with sulphur and accelerators. EPM represents a copolymer from ethylene and propylene monomers; EPM is entirely saturated and therefore requires vulcanization by radiation or products that release free radicals, such as organic peroxides. Its heat resistance is distinctly better than that of Natural Rubber, SBR and Butadiene Rubber. The molecules of both EPM and EPDM have a completely saturated hydrocarbon backbone, through which excellent ozone resistance and very good resistance to heat and oxidation are achieved. Oil Extended and Non-Oil types of EPDM in the shapes of Prime, Near to Prime and Off Grades can be supplied
