PCTFE

PCTFE (polychlorotrifluoroethylene) is a thermoplastic chlorofluoropolymer with the lowest water vapour transmission rate of any plastic.

Well-known brand names used for PCTFE are Kel-F®,  Neoflon® or Voltalef®

PCTFE’s most striking property is its capability to operate and maintain its elasticity at extremely low temperatures, even up to -273°C. It is therefore well suited to cryogenic applications.

PCTFE is non-flammable and resists most corrosive chemicals. It exhibits properties such as zero moisture absorption and is non-wetting. PCTFE also maintains its outstanding electrical-insulating capability through thermal cycling and in high-humidity environments.

This material’s high compressive strength and dimensional stability make it aptly suited for use as a structural material, especially in applications where high temperatures and chemical resistance are required. Combined with its low outgassing (0,01%) and its wide temperature range, it is suitable for use in aerospace.
