Nitrile(NBR)

Nitrile(NBR) rubber is a copolymer of acrylonitrile and butadiene, with excellent resistance to petroleum and non-polar solvents, and good mechanical properties. The specific performance mainly depends on the content of acrylonitrile. Those with acrylonitrile content higher than 50% have strong resistance to mineral oil and fuel, but their elasticity and permanent compression deformation at low temperatures become worse. Low acrylonitrile nitrile rubber has good low temperature resistance, but reduces oil resistance at high temperatures.
