PCTFE Tube

PCTFE (polychlorotrifluoroethylene) is a high-performance fluoropolymer valued for low gas permeability, dimensional stability, chemical resistance and reliable performance at cryogenic temperatures.

Descrição

Applications of PCTFE Tubes

PCTFE tubes are used for cryogenic sealing components, valve and pump parts, high-purity fluid-handling systems, electrical insulation and precision components requiring low moisture absorption and dimensional stability.
