What is Nitrile Butadiene Rubber (NBR)? – Material Overview
Nitrile Butadiene Rubber (NBR) is a copolymer of acrylonitrile (ACN) and butadiene. The ratio of acrylonitrile in the polymer chain directly affects the performance of the rubber:
At RUBASIA, our standard NBR formulation is optimized to balance oil resistance, heat resistance, tensile strength, and elongation, making it suitable for multi-industry use.
