Also known as “Buna” or “Buna-N” rubber. For use in applications requiring a rubber sheet or gasket with high resistance to petroleum based fluids.
Very good resistance to oil and gasoline; superior resistance to petroleum-based hydraulic fluids; wide range of service temperatures; good resistance to hydrocarbon solvents; very good resistance to alkalis and acids.
Inferior resistance to ozone, sunlight and natural aging; poor resistance to oxygenated solvents.
Where oil resistance is the main concern (machinery gaskets, around oil and gas handling equipment, heat and oil resistant belting).
