Nitrile Rubber (NBR, Acrylonitrile-Butadiene Rubber)
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Nitrile Rubbers are copolymers of butadiene and acrylonitrile. The term has also been applied to copolymers of other dienes and/or nitriles. Acrylonitrile content may range from 18-50%. Increasing acrylonitrile content leads to higher hardness, strength, abrasion resistance, heat resistance, and oil/fuel resistance and lower resilience and low temperature flexibility. NBR is generally damaged by ozone, chlorinated solvents, ketones, aldehydes, esters, and nitrogen-containing solvents.
