White Color Custom Parts Molded PTFE Block Sheet Size 50mm 60mm 80mm Thick
DESCRIPTION
Polytetrafluoroethylene (PTFE), commonly known as "non-stick
coating" or "easy-to-clean materials ". This material has the
characteristics of antacid and alkali resistance, resistance to
various organic solvents, and is almost insoluble in all solvents.
At the same time, PTFE has the characteristic of high temperature
resistance, and its friction coefficient is very low.
MAIN PROPERTIES
| Properties | Unit | Result |
| Apparent density | g/m3 | 2.10~2.30 |
| Tensile strength(min) | Mpa | 15.0 |
| Crack elongation(min) | % | 150 |
| Dielectric strength(min) | Kv/mm | 10 |
MAIN FEATURES OF PTFE
1 . Excellent non-sticky property - --With low friction coefficient it
easier to remove those resin, dopes, oil and other sticky things.
2 . Excellent chemical corrosion resistance ---Applicable medium
includes oil, acid solution and almost all chemical materials.
3 . Excellent insulation property.
4 . Temperature resistance ---It is able to work stably between
-180°C to +260°C.
5 . Excellent insulation property.
6 . Anti-aging, weathering resistance.

APPLICATION
has excellent comprehensive properties, high temperature resistance, corrosion resistance, non-stick, self-lubrication, excellent dielectric properties and very low friction coefficient. Used as engineering plastics, it can be made into polytetrafluoroethylene pipes, rods, belts, plates, films, etc. It is generally applied to corrosion-resistant pipes, containers, pumps, valves, radar, high-frequency communication equipment, radio equipment, etc. with high performance requirements. The mechanical properties of PTFE can be greatly improved by adding any filler that can withstand the sintering temperature of PTFE while maintaining other excellent properties of PTFE. The filled varieties include glass fiber, metal, metalized oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL…, etc. the wear resistance and limit PV value can be increased 1000 times.
Polytetrafluoroethylene pipes are made of suspension polymerized polytetrafluoroethylene resin through plunger extrusion processing. Among the known plastics, polytetrafluoroethylene has the best chemical corrosion resistance and dielectric properties. braided packing is a kind of good dynamic sealing material, which is woven from expanded poly (vinyl chloride) strips and has excellent properties such as low friction coefficient, wear resistance, chemical corrosion resistance, good sealing performance, no hydrolysis, no hardening, etc. Gasket seals and lubricating materials used in various media, as well as electrical insulation, capacitor media, wire insulation, electrical instrument insulation, etc. used at various frequencies.
