PTFE Bar is an unfilled PTFE resin suitable for processing a variety of gaskets, seals and lubricants that work in corrosive media, and electrical insulation parts used at various frequencies. Bar (which can contain recycled polytetrafluoroethylene resin) molded by molding, paste extrusion or plunger extrusion.
Basically resistant to all chemicals except some fluorides and alkaline liquids.
Excellent mechanical properties include aging resistance, especially for bending and oscillating applications.

Product Features
Main features of PTFE rod:
1. Temperature resistance ---It is able to work stably between -180°C to +260°C.
2. Excellent chemical corrosion resistance ---Applicable medium includes oil, acid solution and almost all chemical materials.
3. Excellent non-sticky property - --With low friction coefficient it easier to remove those resin, dopes, oil and other sticky things.
4. Anti-aging, weathering resistance.
5. Excellent insulation property.
6. Filled material: Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide.

Application
1. Chemical: It can be used as anti-corrosion material to manufacture various anti-corrosion parts such as pipes, valves, pumps and fittings. For chemical equipment, linings and coatings for reactors, distillation columns and anti-corrosion equipment can be made.
2. Mechanical: It can be used as self-lubricating bearings, piston rings, oil seals and seals. Self-lubricating reduces wear and heat and reduces power consumption.
3. Electronic and electrical aspects: mainly used in the manufacture of various wire and cable, battery electrodes, battery separators, printed circuit boards, etc.
4. Medical materials: It can be used as a material for various medical devices and artificial organs by utilizing its heat-resistance, water-resistance and non-toxic properties. The former such as sterile filters, beakers, artificial heart and lung devices, the latter such as artificial blood vessels, heart and esophagus. It has been widely used as a sealing material and a filling material.
