NBR or BUNA N Chemical name acrylonitrile-butadiene copolymer
Physical properties
NBR is the oil resistance elastomer. The resistance of oil depends on the proportion of acrylonitrile in the rubber. decreasing low temperature flexibility, increasing compression set, gas permeability, improved heat ageing and ozone resistance, improved tensile and abrasion strength, hardness and density.
