(2) The rational performance
Nitrile rubber is acrylonitrile (ACN) and the butadiene copolymer. Nitrile rubber performance mainly depends on the ACN composition (usually 18% - 50%), ACN content more than 50% has strong resistance to mineral oil and fuel ability, but its at low temperature flexibility, compression permanent deformation rate becomes poor. Butadiene higher formula (such as 78%), has good low temperature resistance performance, but also sacrificed in high temperature of oil resistant performance, in short,Nitrile rubber excellent oil resistance and resistance to nonpolar solvent performance, but also has better mechanical performance and air tightness. Suitable for aliphatic hydrocarbon (propane, ethane, mineral oil and grease, fuel have), vegetable oil and animal oil, silicone oil, silicone grease, chemical agent, low temperature dilute alkali salt solution, traces, 100 ℃ the following water medium. But for aromatic solvents, halogenated hydrocarbon, ketone and lipid solvent and strong acid alkali resistance of patience is poor. Nitrile rubber weathering and ozone resistance ability is not strong,But with other materials and, can well solve the problems, such as: nitrile rubber/PVC blend material, it not only has excellent weather resistance and the ozone resistance ability, and flame retardant, rolling, coloring capacity is also very good, add a certain amount of magnetic powder can be made into oil resistance rubber, but its permanent compression deformation is poor.
(3) Temperature range
General level: - 40 ~ 100 ℃
Low temperature resistant level: - 55 ~ 100 ℃
High temperature resistant level: - 30 ~ 125 ℃ (air) - 30 ~ 150 ℃ (oil)
(4) Hardness range
shore A40 degree to 93 degree.
Black, brown, green, white, red, yellow, blue, orange, gray, also can have the customer to assign the color.
Acrylonitrile butadiene rubber in various oil resistance occasions is widely used. Car electronic injection of fuel injector parts, all kinds of oil resistance of gaskets, seals, rubber hose. Hydraulic pneumatic industry seal, cushion and other oil resistance, abrasion resistance rubber product. In the nuclear industry, high saturation nitrile rubber because of its resistance to radiation, but also can be used for nuclear power plant of seal.
