What is Vespel® CR-6100?

Vespel® CR-6100 is a composite material made from long carbon fibers and Teflon® PFA resin. Since 1997, Vespel® CR-6100 has been used across the hydrocarbon processing and other fluid handling industries to replace wear components made from metal, carbon, and other composites. Vespel® CR-6100 is made with a unique manufacturing process which orients the fibers in an x-y plane. For a wear part in a rotating machine, the x-y plane is the plane perpendicular to rotation. Below are some of the properties of Vespel® CR-6100 which make it ideal for rotating equipment wear components:

  • Temperature capabilities from cryogenic to 500⁰F (260⁰C)
  • Coefficient of thermal expansion less than carbon steel (in the x-y plane)
  • Near-universal chemical compatibility. We have not yet found a fluid used in the hydrocarbon processing industry which is chemically incompatible with Vespel® CR-6100.
  • Ease of machining and installation
