Freudenberg Sealing Technologies 80 NBR 94207 Nitrile Butadiene Rubber
Categories:	Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Nitrile rubber exhibits superior mechanical strength with high elasticity as well as good deformation behavior. Its relatively low heat resistance can be traced to the presence of reactive double bonds. It is used for oil- and fuel-resistant seals such as Simmerrings®, O-rings and frame seals. The use of NBR marked the arrival of elastomers as a sealing material particularly in general industry. Information provided by Freudenberg Sealing Technologies.
