Nitrile Rubber (NBR – acrylonitrile butadiene copolymer) has good mechanical properties when compared with other elastomers, together with high wear resistance. Nitrile-based compounds can exhibit excellent compression set properties, and has very good tear and abrasion resistance. Nitrile is often used where a seal is required for contact with oil at low temperature.
The majority of O-ring seals are manufactured from Nitrile and commonly used across the whole industrial spectrum.
Examples of products include automotive hose seals and gaskets.
