Molded Extruded PCTFE Polychlorotrifluoroethylene Plastic Rod Bar Diameter 20-160mm
There are two kinds of PTFE rods to offer,One is manufactured by paste
extruding method in the diameter from 4 to 9mm and the other is made by ram ertuding method is the method is the diameter from 10 to 50mm; rods over the diameter 50mm are manutactured by moulding.
PTFE is the most chemical-resistant of all known plastics. It does not age.
PTFE has a wide range of practicalble temperature from -180° C to +260C and a wax -like surface to which anything hardly hardly sticks.
PTFE has the lowest coefficient of friction of all known solid materials. It has the best electrical proper-ties of all plastics.
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 can design and manufacture your product, part or component in PCTFE. Whether developing a new part from scratch or innovating to provide a new solution for a failing component, our engineers can design and manufacture products in PCTFE that will meet and exceed performance requirements.
application:
1. Contact with highly corrosive media, sealing and gasket materials of high-pressure systems, transparent materials for observation windows, etc.
2. Electrical insulation materials, etc.
3. Low molecular weight PCTFE is used as sealing fluid, grease for highly corrosive media and balancing fluid for navigation gyros.
PCTFE rod offers outstanding chemical resistance and cold flow resistance, making it ideal for demanding applications.
