Trade names:

Fluorel® - 3M,  Fluoroelastomer, 
Viton® - DuPont Performance Elastomers.

Compounds of these polymers exhibit excellent resistance to petroleum products, low compression set and high temperature resistance.  The low temperature capability is somewhat restricted, however, in some cases the flow temperature sealing capability may be increased by specific design parameters.  These materials meet the stringent Aerospace Specifications AMS 7278, AMS 7279, and AMS 7280.  They are especially good for hard vacuum services and low gas permeability.  The normal temperature service range is:
 -200F to +4000F/ +4500F.
