The EP(D)M produced by Kumho Polychem is a highly functional special synthetic rubber that is mainly used for automotive parts and has excellent resistance to heat, ozone, and chemicals. With a lower specific gravity compared with other synthetic rubbers, it can be applicable for high-filling mixing, meaning it has a high economic feasibility, making it widely applicable in various areas such as automotive body sealing, tire tubes, hoses, electric wires, and subsidiary construction materials.
Physical outlooks of the EP(D)M Synthetic Rubber are white solid, stable in room temperature. Products containing extender oil show yellow color, and the products used for blending thermoplasticity are transparent pellet. Physical properties of EP(D)M Synthetic Rubber is listed in the table below.
