PTFE rod 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. Rods molded by molding, paste extrusion or plunger extrusion processes.
The temperature range is very wide (from -200 degrees Celsius to +260 degrees Celsius).
Basically resistant to all chemicals except some fluorides and alkaline liquids.
Excellent mechanical properties include aging resistance, especially for bending and oscillating applications.
Outstanding flame retardancy
Excellent insulation properties (regardless of frequency and temperature)
The water absorption rate is extremely low, and it has a series of unique properties such as self-lubricating and non-stickiness.

Product Features
Main features of Filled with Carbon Graphite Black 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.
Even if PTFE rods have excellent properties, like high/low temperature resistance, chemcial resistance, weathering resistance, dielectric superiority and high lubricity, sometimes we still need to improve its hardness, wear resistance, creep resistance and dimensional stability.
Filled PTFE rods 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
PTFE filled modified products: In order to improve the creep properties and wear resistance of PTFE, the PTFE is filled and modified. The main materials are graphite, carbon black, molybdenum disulfide, glass fiber, carbon fiber, polyphenylene sulfide etc.
Teflon is the heaviest of the plastics. It has a wide range of operating temperatures (-250~260°C), good chemical stability, excellent dielectric properties, self-lubricity and anti-stick properties, so it has a wide range of applications
It can be used as an anti-corrosion material in chemical industry to manufacture various anti-corrosion parts such as pipes, valves, pumps and fittings. Chemical equipment, lining and coating of reactors, distillation towers and anti-corrosion equipment.
Mechanically, it can be used as self-lubricating bearings, piston rings, oil seals and seals. Self-lubricating reduces wear and heat and reduces power consumption.
Product Packaging
Packed by plastic bags,put into Plywood cases that don't need fumigation. Other packing is customized according to client's requirements.
