EPDM boasts a number of outstanding properties. Not only is it resistant to weather and ozone as well as heat and cold, but it also possesses outstanding electrical characteristics and chemical resistance. Widely used in applications ranging from automotive parts to electric wire sheathings and cables and other industrial parts, EPDM is expected to experience rapid expansion in demand driven by growth exceeding 10% per year in automobile output, in particular, in the Asian region. At the same time, thermoplastic vulcanizates (TPV), which contains EPDM as a main raw material, is seeing demand growth globally as applications for this eco-friendly material expand to mainly automobile interior materials, construction materials and electronic appliances. EPDM's light-weight and recyclable features contributes a lot to its eco-friendliness.
