Nitrile rubber compound (NBR)

Nitrile rubber compound (NBR)

Nitrile rubber compound (NBR) is a compound that can be directly molded and processed by mixing nitrile rubber as raw rubber and adding vulcanizing agent, accelerator, reinforcing agent, softener and other compounding agents. It is the most widely used oil-resistant sealing material in the industry.
Product Features

Excellent oil resistance:Excellent resistance to engine oil, fuel oil, aliphatic hydrocarbon oil, etc. (the higher the acrylonitrile content, the better the oil resistance).

Wear resistance, heat resistance, good air tightness:Can be used in 120 ℃ air or 150 ℃ oil for a long time.

Hardness range:Shore A 20~95 degrees, can be customized.
