Properties of Nitrile Rubber (NBR)
Nitrile rubber (NBR), a synthetic copolymer of butadiene and acrylonitrile, is widely valued for its exceptional resistance to oils, fuels, and chemicals. Commonly used in seals, gaskets, and hoses, NBR is a versatile elastomer in automotive, aerospace, and industrial applications where durability and chemical compatibility are critical.
The following table provides a comprehensive list of nitrile rubber (NBR) properties in both SI and US customary/Imperial units at normal temperature and pressure (NTP).
