Product Description

                            PCTFE tight seals at extremely low temperatures -400F for Cryogenic Valves seals
PCTFE tight seals at extremely low temperatures -400F for Cryogenic Valves

PCTFE from Polyfluor is especially suitable for cryogenic applications because the material can withstand very low temperatures. PCTFE is a kind of perfect sealing material under low temperature, high vacuum system and high pressure working conditions.

It has excellent rigidity, low temperature resistance, cryogenic fluid resistance, and airflowresistance.
Further, PCTFE from Polyfluor has the following properties:

. excellent low temperature resistant
. Good mechanical property
. Low coefficient of liner expansion
. Good dimensional stability
. Good penetration function

Over 25 years experience in the field of Fluoropolymer (PVDF, PFA, PCTFE, PTFE, FEP, ETFE)
The leading fluoropolymer manufactuer in China and global supplier of high performance plastics shapes and machined components.
We produce PCTFE Rods, PCTFE Sheets, PCTFE tubes and PCTFE seals& PCTFE seats as per drawing.

Product application

PCTFE is widely used for seals in the condition of low temperature with high pressure(gas, liquid nitrogen, liquid oxygen ect) ,semiconductor, chemical, pharmaceutical,aerospace and other relevant sealing area.
