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
Limitations
poor resistance to outdoor weathering without special compounding
comparatively low strength
flammable and burns with toxic fumes
Typical Applications
sealing in enclosed spaces where there is contact with petroleum based fluids
