Nitrile butadiene rubber is a synthetic copolymer derived from the polymerization of butadiene and acrylonitrile. The proportion of acrylonitrile in the polymer chain determines the rubber’s properties, with higher acrylonitrile content offering greater resistance to oils and fuels but reduced flexibility at low temperatures. NBR is classified into several grades based on its acryloni... https://www.polarismarketresearch.com/blog/top-20-nitrile-butadiene-rubber-manufacturing-companies-in-2025
