NBR NBR oil resistance is good, energy and most of the mineral base oil and grease compatibility. But not for phosphate ester series hydraulic oils and gear oils containing polar additives, intolerance of aromatic hydrocarbons and chlorinated hydrocarbons, ketones, amines, anti-natural liquid HFD. -40 To +120 manufacture O-ring, oil seal and so on. For general hydraulic oil, water glycol HFC and oil in water emulsions HFA, HFB, animal oil, vegetable oil, fuel oil, boiling water, water resistance, A, B, C, butane.

　　RP rubber composite material elastic modulus, high strength. Performance with the rest of NBR. -30 To +120 for the manufacture of O-ring, Y-ring, dust ring. Used in engineering machinery hydraulic system seals.

　　Viton FKM or FPM heat, acid and other chemicals. Oil (including phosphate ester series hydraulic oil), applies to all oil, gasoline, hydraulic oil, synthetic oil and so on. Resistant natural liquid HFD, fuel, chain hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons and most inorganic acid mixture. But intolerance ketones, amines, anhydrous ammonia, low molecular weight organic acids, formic acid and acetic acid cases. -20 To +200 is characterized by high temperature resistance, weather resistance, ozone and chemical media, almost all of the resistant mineral based and synthetic-based hydraulic oil. But the case of steam, hot water or low temperature applications, have some limitations. Its low temperature performance is limited, and the compatibility of steam and hot water medium, in case such an occasion, to use special fluorine rubber. Flame sealing hydraulic oil, metallurgy, electric power and other industries widely used.
