Acrylonitrile Butadiene (NBR - Nitrile)

Nitrile Rubber (NBR) is the general term for Acrylonitrile Butadiene Polymer. Acrylonitrile content varies from 18 to 50%. Higher the Acrylonitrile content, better the resistance to fuel and oil, at the same time affecting elasticity & compression set.

-300C to 1000C

Chemical Resistance:
Propane, Butane, Petroleum, Mineral Oil, Grease, Diesel Fuel, Fuel Oils, HFA, HFB, HFC Fluids, Dilute Acids, Alkali, Salt Solutions and Water.

Carboxylated Nitrile (XNBR)

Carboxylated Nitrile has proven tear and abrasion resistance compared to NBR. It is often used for dynamic applications.

TEMP: - 300C to 1000 C

Hydrogenated Nitrile (HNBR)

NBR compounds exhibits improved heat resistance to the general NBR compounds. They also possess superior mechanical properties particularly high strength.

TEMP: -400C to 1500 C

Fluorocarbon (FKM - Viton ®)

FLUOROCARBON (FKM - VITON ®) has excellent resistance to High temperature, Ozone, Oxygen, Mineral Oils, Aliphatic and Aromatic Hydrocarbons and many chemicals.

TEMP: -200C to 204 0 C

Chemical Resistance:
Mineral Oil, Grease, Non Flammable Hydraulic Fluids, Aliphatic and Aromatic Hydrocarbons, Ozone Weathering, Aging, High Vacuum, Steam and Alcohol.

O-Rings are manufactured from over 15 different Polymers which include
