Acrylonitrile Butadiene Rubber (NBR)
Advantage:
1. Has good solvent, oil, water and hydraulic fluid resistance.
2. Good compression set, abrasion resistance and tensile strength.
Disdvantage:
1. Not recommended for using in highly polar solvents such as acetone, and MEK, ozone, chlorinated hydrocarbons and nitro hydrocarbons.
