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
