EPDM molecular structure of the main chain do not contain a double bond, so the ozone resistance and oxidation resistance is superior. Can be long-term under the natural environment of light, damp, cold, weather resistance is superior. Due to main chain saturated structure so it has excellent resistance to high temperature performance, can be long-term use under condition of 120 ℃, the highest temperature 150 ℃. Due to its glass transition temperature between - 35 ℃ ~ 65 ℃, when most sulfide products - 50 ℃ still very soft, so there is still a softness in low temperature and low compression permanent deformation, so at low temperature has good sealing performance, and easy to construction in winter. Its resistance to a variety of polar solute, including brake oil, acid, alkali, alcohol, etc., poor resistance to nonpolar solutes, such as gasoline hydrocarbons solute. Can be applied to high temperature, cold, coastal, ultraviolet irradiation using strong area.
My company is based on EPDM rubber as the main raw material with various additives by reasonable formula, strict production process, advanced microwave curing equipment to produce the chemical crosslinking of products, it is a kind of pure rubber material. It has a rubber variety of excellent performance, such as low compression deformation, good low tender and soft, high tensile strength, good abrasion resistance, excellent resistance to oil or solvent soluble rise, excellent resistance to ultraviolet radiation ageing and climate. It is as good as sealing material. It is suitable for all kinds of doors and windows to use. Suitable for China's vast geographical features of EPDM sealing strip, suitable temperature of 60 ℃ to 150 ℃.
Such products are mainly used with car, train, plane, ship, high building high-grade doors and windows dynamic and static seal.
