Ethylene propylene diene monomer (EPDM) is made from ethylene, propylene, and a diene comonomer. This material is known for its durability, flexibility, resistance to extreme temperatures and many other properties. It has a broad range of applications, including automotive parts, waterproofing coils, wire and cable insulation, heat-resistant hoses, and heat-resistant shipping tapes. Although it performs well at extreme temperatures, it does not possess good flame retardancy. For its safety in use, EPDM has to be treated with flame retardants.
