Oil-Resistant Nitrile Butadiene Rubber — Nitrile Butadiene Rubber (Oil-Resistant)
NBR is a copolymer of butadiene and acrylonitrile, providing superior resistance to oils and solvents compared to natural rubber. The higher the acrylonitrile content, the better the oil resistance, but flexibility at low temperatures decreases.
