Nitrile rubber is a copolymer of acrylonitrile and butadiene. It has excellent resistance to petroleum and non-polar solvents, as well as good mechanical properties. The specific performance mainly depends on the content of acrylonitrile. Those whose acrylonitrile content is higher than 50% have strong resistance to mineral oil and fuel oil, but their elasticity and permanent compression deformation at low temperature become worse. Low acrylonitrile Nitrile rubber has good low temperature resistance, but reduces the oil resistance at high temperature.
Advantages:
1. Good oil, water, solvent, and high-pressure oil resistance characteristics
2. Good compression resistance, wear resistance, and tensile properties
3. Rubber parts used for making fuel tanks and lubricating oil tanks
4. Rubber parts used in fluid media such as petroleum based hydraulic oil, gasoline, water, silicone grease, silicone oil, diester based lubricating oil, and glycol based hydraulic oil
Disadvantages:
1. Not suitable for use in polar solvents such as ketones, ozone, nitrohydrocarbons, MEK, and chloroform
2. Not resistant to ozone, weather, and heat air aging
Applicable medium:
1. Fatty hydrocarbons (butane, propane), engine oil, fuel, vegetable oil, mineral oil
2. HFA, HFB, HFC hydraulic oil
3. Low concentration acids, alkalis, salts, and water at room temperature
