Description:

Nitrile is the combination of butadiene and acrylonitrile. Butadiene provides elasticity and low-temperature flexibility, resistance to heat, chemicals, and oxidation. Acrylonitrile provides hardness, tensile strength and creates resistance to abrasion, fuel, and oil. A standard general-purpose nitrile compound usually contains 34% ACN (Acrylonitrile).

Advantages:

Excellent tensile strength, abrasion, tear and compression resistance. It is used in water and steam applications (below 212°F), petroleum oils and fuels, silicone oils and greases, propane, ethylene glycol, butane, vegetable, mineral oils and greases, and dilute acids.

Disadvantages:

Low resistance to ozone, sunlight, and weathering. Incompatible with benzene, toluene, xylene, halogen derivatives (carbon tetrachloride, trichloroethylene), ketones (MEK, acetone), phosphate ester hydraulic fluids (Skydrol, Pydraul), strong acids and glycol.
