PCTFE / (Kel-F® / Neoflon®)
PCTFE (polychlorotrifluoroethylene), sometimes referred to as Kel-F® (a discontinued product from 3M) or Neoflon® (a product of Daikin Industries), combines physical and mechanical properties, non flammability, chemical resistance, near-zero moisture absorption and excellent electrical properties not found in any other thermoplastic fluoropolymer that also performs well in a temperature range of -400° F to 400° F. PCTFE also has high compressive strength, an exceptional resistance to cold flow and is optically transparent. 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 very low outgassing rate and permeability make PCTFE a good choice for instrumentation, laboratory, aerospace and flight applications. Other common applications include cryogenics, valves, seals, and film for food and pharmaceutical packaging.
