HNBR is a partially or completely hydrogenated acrylonitrile-butadiene rubber.
•    HNBR is serviceable over a range of temperatures from -40°C to 160°C
•    Excellent long-term temperature resistance obtainable with HNBR
•    Excellent resistance to many automotive fluids such as engine oils, ATF, power steering fluid and coolants
•    Excellent resistance to many modern fuels including biodiesel
•    Resistance to hydrogen sulfide and amines
•    Resistance to acids and alkalis
•    Resistance to steam
•    Resistance to ultraviolet (UV) radiation
•    Low noise/vibration transmission

Typical Applications
•    Automotive
•    Oil Industry
•    Petroleum Refining and Transportation
•    Electrical Industry
•    Mechanical Engineering Industry
•    Ship Building Industry
