NBR represents the same elastomer based on a butadiene and acrylonitrile copolymer.

 

Nitrile is inherently resistant to:


  • Hydraulic fluids
  • Lubricating oils
  • Other non-polar petroleum-based products
  • Air and water environments 

 

General Properties

Excellent resistance to petroleum-based fluids and good physical properties 

Resistant to 

 Many hydrocarbons, fats, oils, greases, hydraulic fluids, chemicals 

Attacked by 

Ozone (except PVC blends), ketones, esters, aldehydes, chlorinated and nitro hydrocarbons 

General Polymer Characteristics
 Abrasion Resistance  Good    Gas Permeability  Good
 Compression Set  Excellent  Low Temperature Flexibility  Good
 Elongation  Good  Tear Resistance   Good
 Flame Resistance  Poor
