Nitrile Rubber / NBR #1
NBR is an acrylonitrile-butadiene copolymer, and it is a rubber that excels significantly in oil resistance.
It is broadly used in automotive parts and industrial goods.
* Excellent oil and gasoline resistance.
* Excellent processability, easy and fast curing.
* Excellent cured physical properties.
ENEOS Materials has a broad range of grades to meet the demand.
