PCTFE, Polychlorotrifluoroethylene is a melt-processable chlorofluoropolymer. PCTFE rod,also known as kel-f rod. Kel-F, Neoflon M300H or M400H PCTFE, polychlorotrifluorethyene, is the homopolymer of chlorotrifluorethylene. Kel-F or PCTFE, offers the unique combination of physical and mechanical properties, nonflammability, high optical transparency, chemical resistance, near zero moisture, and excellent electrical properties that cannot be found in other thermoplastic fluoropolymers. It has a useful temperature range of -240 degrees C to +120 degrees

PCTFE is a kind of perfect sealing material under cryogenic and high pressure conditions. We can manufacture PCTFE tubes over 680 mm in diameter to be used in the production of seal rings or valve seats. With over more then 20 years production experience in this field, we can offer full sizes PCTFE tube from size 30mm OD to 700mm OD.

Compared with pctfe rod, our full range of PCTFE tubes made by mould compression can help customers to save material and lower down cost when do machining of bigger size pctfe seal rings or pctfe gaskets.

PCTFE has a low melt viscosity which permits extrusion, compression moulding and injection moulding. Typical uses include valve seats, seals, sight glasses and windows and many cryogenic applications.

We manufacture PCTFE semi-finished products including pctfe rod, pctfe tube and pctfe sheet by extrusion and compression moulding.

PCTFE is recommend

ed for cryogenic application and handling of gases. Hongda supply PCTFE tube in various diameters.
