PCTFE
With excellent rigidity, low temperature and cold flow resistance, PCTFE (PolyChloroTriFluoroEthylene) is an ideal sealing material under the condition of low temperature and high pressure in enormous high-tech fields.
Features:
PCTFE contains 49% fluorine. It has high compressive strength, high hardness, creep resistance, lowest moisture vapor transmission rate and very low gas permeance rate. Infrared, ultraviolet and visible lights can easily penetrate through PCTFE.
