About PCTFE material

PCTFE, the full name is Polychlorotrifluoroethylene, also be called as PTFCE, is a thermoplastic chlorofluoropolymer. Compared to PTFE (Teflon), PCTFE offers higher strength, meantime, PCTFE is resistant to the attack of most chemicals and oxidizing agents, due to the presence of high fluorine content.

PCTFE material offers the highest limiting oxygen index and excellent chemical resistance, it is also exhibits properties like zero moisture absorption and non-wetting. It can work well at temperature from -240 to 200 °C, meantime, it offers a great dimensional stability and low coefficient of thermal expansion. Therefore, PCTFE material is an indispensable material in aerospace, electrical, medical, cryogenic valve, and nitrogen generation, etc.

PCTFE material can be processd by injection moulding, extrusion and compression moulding. The frequently used profiles are sheets, rods, tubes, etc.
