DuPont™ Kalrez® – High Performance Perfluoroelastomer Parts

kalrez-2Kalrez® parts last longer and seal more effectively than other elastomers in demanding processing environments.
DuPont™ Kalrez® perfluoroelastomer (FFKM) parts resist over 1,800 different chemicals, while offering the high temperature stability of PTFE (327°C).

They’re used in highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceutical, oil and gas recovery, and aerospace applications. The long-term, proven performance of Kalrez® parts can mean less frequent seal changes, repairs and inspections, increasing process and equipment uptime for greater productivity and yield.

Kalrez® parts and seals also help prevent semiconductor process contamination by reducing particulates, lowering extractables, and resisting degradation in harsh plasma. Kalrez® parts provide low outgassing in vacuum-sealing applications. FDA-compliant seals are also available for food, beverage or pharmaceutical processes.

Chemraz® – The Ultimate Elastomer for Oilfield Applications

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.
