Nitrile rubber is used for acrylonitrilebutadiene rubber (NBR). This material has very good engineering properties and is a general purpose sealing lip material. It is a copolymer manufactured from acrylonitrile and butadiene that provides good resistance to the following media.
- • Most mineral oils and greases with a mineral oil base
- • Normal fuels like gasoline, diesel and light heating oils
- • Animal and vegetable oils and fats and hot water
Nitrile rubber also tolerates short-term dry running of the sealing lip. The permissible operating temperature range of nitrite rubber is -40 to +100 °C (-40 to +210 °F). For brief periods
