Nitrile
Another early development in the search for an oil resistant rubber. The most suitable rubber for applications requiring resistance to petroleum based fluids (there are rubbers with higher degrees of resistance but these are much more expensive).
Properties
- very good resistance to petroleum based fluids
- good high temperature resistance – up to 100°C (120°C with EV cure systems)
- economical to compound and produce
- very low level of permeability to gases
