PCTFE

OMEGA-CRYO ® Polychlorotrifluoroethylene (PCTFE) is melt-processible fluoropolymer with a continuous use temperature range from -205ºC up to 150ºC.

OMEGA-CRYO ® has high compressive strength, low deformation under load (its cold flow is lower than that of other fluoropolymers), chemical and thermal stability, low gas permeability, high optical transparency, low flammability and zero moisture absorption. Because PCTFE is a highly fluorinated resin, it is nonflammable and resists most corrosive chemicals. It also maintains its outstanding electrical-insulating capability through thermal cycling and in high humidity environments. The product’s high compressive strength and dimensional stability make it a good choice for structural material, while its low outgassing rate and permeability make PCTFE a good choice for instrumentation, laboratory, aerospace, flight applications, cryogenics, valves, seals and films for food and pharmaceutical packaging.
