Carboxylated Nitrile 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 wipers.
Heat resistance
• Up to 100°C (212°F) with shorter life @ 121°C
(250°F).Cold flexibility
• Depending on individual compound, between -18°C
and -48°C (0°F and -55°F).
Chemical resistance
• Aliphatic hydrocarbons (propane, butane, petroleum
oil, mineral oil and grease, Diesel fuel, fuel oils) veg¬etable
and mineral oils and greases.
• HFA, HFB and HFC fluids.
• Many diluted acids, alkali and salt solutions at low
temperatures.
• 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, ethylene-ester).
• Strong acids.
• Brake fluid with glycol base.
