Chemraz® is a trademark of Greene Tweed and is a member of the perfluoroelastomer polymer family—polymers of three or more monomers in which all hydrogen positions have been replaced with fluorine. This complete state of fluorination results in outstanding resistance to heat and most chemicals and solvents. The principle monomer of Chemraz is tetrafluoroethylene (TFE); the proprietary second and third perfluorinated monomers are unique to it and confer the balance of the properties it demonstrates. Chemraz’s resistance to steam and significantly improved low temperature properties are its hallmark.

Chemraz gives excellent sealing performance when exposed to mixes of aggressive chemicals found downhole in oil operations. Special compounds have been formulated for improved resistance to rapid gas decompression and abrasion.

Chemraz compounds are compatible with all well fluids and gases and injection and treatment chemicals, including reservoir fluids with high H2S content, stimulation treatment fluids, completion fluids and asphaltene removers such as Xylene and Toluene together with amine-based inhibitors.

Typical Applications:

  • Subsurface safety valves
  • Packers
  • Geothermal applications
  • Logging tools
  • Wireline tools
  • Drillstem test tools

Chemraz is available in a small number of sizes, with other sizes available through special order. Check the O-ring Special Materials sections of our website for in stock items 24/7 or call us at 1 (800) 445-7803.
