PCTFE ring, PCTFE gasket
PCTFE is a copolymer that contains 49% fluorine. It has high
compressive strength, high hardness, creep resistance, lowest
moisture vapor transmission rate and very low gas permeance rate.
Infrared, traviolet and visible lights are easily to penetrate
through PCTFE. It also has excellent properties under low
temperatre. PCTFE is a good mechanical sealing material in
conditions of high pressure and low temperature.PCTFE also has extremely low outgassing, making it well suited for
use in aerospace and flight applications.
