Carboxylated Nitrile (XNBR) is a special type of nitrile
polymer that exhibits enhanced tear and abrasion resistance.
For this reason, XNBR based materials are often
specified for dynamic applications such as rod seals and rod
• Up to 100°C (212°F) with shorter life @ 121°C (250°F).
• Depending on individual compound, between -18°C
and -48°C (0°F and -55°F).
• Aliphatic hydrocarbons (propane, butane, petroleum
oil, mineral oil and grease, Diesel fuel, fuel oils)
vegetable and mineral oils and greases.
• HFA, HFB and HFC fluids.
• Many diluted acids, alkali and salt solutions at low
• Water (special compounds up to 100°C) (212°F).
Not compatible with:
• Fuels of high aromatic content (for flex fuels a special
compound must be used).
• Aromatic hydrocarbons (benzene).
• Chlorinated hydrocarbons (trichlorethylene).
• Polar solvents (ketone, acetone, acetic acid, ethyleneester).
• Strong acids.
• Brake fluid with glycol base.
