NITRILE (NBR)

Nitrile (also known as NBR rubber and Buna-N) is the seal industry’s most widely used and economical elastomer. This is partly because it displays excellent resistance to petroleum-based oils, fuels, water, alcohols, silicone greases and hydraulic fluids. Nitrile has a temperature range of between -54 and +149 degrees Celsius and has a good balance of desirable properties like low compression set, high abrasion resistance and high tensile strength. It not advisable for use with automotive brake fluid, ketones, phosphate ester hydraulic fluids, and nitro or halogenated hydrocarbons.
