Nitrile (NBR/Buna)


Nitrile is the most widely used elastomer, due to its excellent resistance to petroleum based oils, and fuels, hydraulic fluids, water and alcohols. It provides a good balance of working properties, including low compression set, high tensile strength and high abrasion resistance. Nitrile is the most cost-effective material, making it a popular choice for a wide range of applications.

Our NBR is available as High Nitrile, Low Nitrile, and can be FDA and/or WRAS Approved.
