Chemraz® 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 it’s hallmark.
Chemraz—the ultimate elastomer for demanding oilfield applications—gives excellent sealing performance when exposed to mixes of aggressive chemicals found downhole and is often specified by operators. Special compounds have been formulated for improved resistance to rapid gas decompression and abrasion, giving significant reductions in downtime and maintenance.
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. Chemraz is available in O-ring, Vee ring, G-T® ring, electrical connector boots, slabs, metal bonded seals, Arlon® thermoplastic bonded seals, miniature seals, diaphragms and custom configurations.
