Nitrile (NBR)

General Guidelines

Common Name: Nitrile, Buna, NBR, Buna-N

Chemical Name: Acrylonitrile – Butadiene

Properties: Excellent resistance to oil/gasoline, petroleum based hydraulic fluids. Wide range of service temps, very good resistance to alkalis and acids.

Size Sheet Range: Width: .75” -60” Thickness: .010” – 1.00” Length: Min 60’Ft
Uses: In and around oil and gas exposed areas, hose, wire & cable

Note-Property values are all based on cured elastomers
