Product Description

Nitrile (NBR) provides excellent resistance to petroleum oils and gasoline as well as mineral and vegetable oil. It also offers strong resistance to heat aging—often a key advantage over natural rubber. Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but those applications requiring resistance to heat, abrasion, water, and gas permeability.

Additional features/information about NBR (nitrile):

• Good resistance to acids and bases except those having strong oxidizing effects
• Poor resistance to the swelling action of oxygenated solvents such as acetone and ketones
• Higher acrylonitrile contents increase solvent resistance but decrease low-temperature flexibility
• Compounding to improve low-temperature flexibility decreases oil and solvent resistance
• Reinforcing materials are required to obtain high strength because it does not crystallize on stretching
• With compounding, it is possible to get a fairly good balance between low creep, good resilience, low permanent set and good abrasion resistance
• Tear resistance and electrical insulation properties are inferior to natural rubber
