EPDM (Ethylene propylene Rubber) is made of ethylene and propylene copolymerization, so heat resistance, aging resistance, ozone resistance, stability are very good, but not sulfur sulfur .To solve this problem, in the EP The main chain into a small amount of double-stranded third component can be added to the vulcanization of sulfur EPDM, the general use temperature of -50 ~ 150 ° C. Of polar solvents such as alcohols, ketones and other excellent resistance Advantages: And anti-ozone, with excellent water resistance and resistance of words, can use alcohols and ketones, high temperature steam, the gas has a good impermeability. Disadvantages: Not recommended for food use or exposure to aromatic hydrogen. Seals for high temperature steam atmospheres - Seals or components for sanitary equipment. Rubber parts in brake (brake) systems. Radiator (car water tank) in the seal.
