PCTFE ring, PCTFE gasket
Features
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.
