Buna N, a copolymer of butadiene and acrylonitrile.
High tensile strength, as well as good tear and compression set resistance, very good aging properties under severe operating conditions.
Nitrile performs well in: Dilute acids, Ethylene glycol, Petroleum oils and fuels, Silicone oils and greases and Water (below 212° F)
Does not have good resistance to ozone, sunlight, or weathering, and should not be stored near ozone-generating electric motors or equipment.Nitrile does not perform well in: Aromatic hydrocarbons (benzene, toluene, xylene), automotive brake fluid, Halogen derivatives (carbon tetrachloride, trichloroethylene), Ketone (MEK, acetone), Phosphate ester hydraulic fluids (Skydrol®, Pydraul®) or Strong acids
General Temperature Range:
Hardness Range 30 – 90 Shore A
Tensile 1000 psi 1.0 – 3.5
Elongation max 600 %
Compression Set excellent moderate low can be compounded to requirements
