Nitrile rubberIt is acrylonitrile and butadiene copolymer and has excellent resistance to oil and non-polar solvent properties, but also has good mechanical properties. Specific performance depends on the content of one of the acrylonitrile component, acrylonitrile content above50%Who has a strong resistance to mineral oil and fuel capacity, but its elasticity at low temperatures and a compression worse, low acrylonitrile butadiene rubber has good low temperature performance, but reduces oil resistance at high temperatures.

Benefits:

Features * good oil, water, solvents and high pressure oil

·Good pressure change performance, wear resistance and tensile properties

·Rubber parts for the production of the fuel tank, oil tank of

·For petroleum-based hydraulic oil, gasoline, water, silicone grease, silicone, diester-based lubricants, glycol lines

Hydraulic oil fluid medium used rubber parts

Disadvantages:

·Not being suitable for use in polar solvents, such as ketones, ozone, nitro hydrocarbons,MEKAnd chloroform

· Resistant to ozone, not the weather, not hot air aging

Medium:

·Aliphatic hydrocarbons (butane, propane), engine oil, fuel oil, vegetable oils, mineral oil

·HFA,HFB,HFCHydraulic oil

·Normal low concentration of acid, alkali, salt
