NITRILE RUBBER (NBR)
- Nitrile rubber or rubber, is the synthetic rubber that offers better chemical resistance and temperature capacity than neoprene.
- Good resistance to hydrocarbons and oils.
- Not recommended for chlorinated hydrocarbons, esters, ketones and strongly oxidizing agents.
- Excellent resistance to high temperatures.
