Polymeric compound of butadiene and nitrile-acrylic. The nitrile-acrylic portion can be between 18 and 50% of the formulation. Good resistance to swelling in :
Aliphatic hydrocarbons, e.g. propane, butane, petrol, mineral oils (lubricating oils, hydraulic oils of groups H, H-L and H-LP) and in mineral oil-based greases, flame-retardant hydraulic fluids of groups HFA, HFB and HFC, vegetable and animal oils and fats, light fuel oils, diesel oil.
Good resistance to swelling in:
Fuels with high aromatic content (Superfuel).
Strong swelling in:
Aromatic hydrocarbons, e.g. Benzol, chlorinated hydrocarbons, e.g. Trichloroethylene, hardly flammable hydraulic fluids of the HFD group, esters, polar solvents, as well as glycol-based brake fluids, e.g. ATE and pentosin.
Thermal use range:
Between -30°C and +100°C. At high temperatures the material hardens.
