1. ptfe tube
PTFE tube (PTFE) has excellent chemical stability, can withstand all strong acids, strong bases, strong oxidants, and does not work with various organic solvents.
PTFE tube has a wide range of temperature, and can be applied to -180 ℃ ~ 250 ℃ for a long time under normal pressure. After being treated at 250 ℃ for 1000h, its mechanical properties change very little.
PTFE tube has a very low friction coefficient, is a good antifriction, self-lubricating material, its static friction coefficient is less than the dynamic friction coefficient, so used to make bearings have the advantages of small starting resistance, smooth operation. Because PTFE is non-polar, heat-resistant and non-absorbent, it is also an excellent electrical insulating material. Also has excellent aging resistance, non-sticky and non-flammable.
PTFE tube Chinese trade name "Teflon" (teflon), "Teflon", "Teflon", "Teflon" and so on. It is a polymer compound formed by polymerization of tetrafluoroethylene. Its structure is-[-CF2-CF2-]n-. It has excellent chemical stability and corrosion resistance. It is one of the best corrosion resistance materials in the world today. In addition to molten alkali metals, chlorine trifluoride, chlorine pentafluoride and liquid fluorine, it can withstand all other chemicals and will not change when boiled in aqua regia, it is widely used in all kinds of occasions that need to resist acid and alkali and organic solvents.
Ptfe pipe has sealing, high lubrication non-stick, electrical insulation and good anti-aging ability, excellent temperature resistance (can be in the positive 250 ℃ to negative 180 ℃ temperature for a long time). Teflon itself is not toxic to humans. The use temperature is -190~250 ℃, allowing quenching and quenching, or alternating hot and cold operation. Pressure -0.1~6.4Mpa.

The production of PTFE has solved many problems in chemical, petroleum, pharmaceutical and other fields. PTFE seals, gaskets, gaskets. PTFE seals, gaskets, sealing gaskets are made of suspension polymerization PTFE resin molding. Compared with other plastics, PTFE has the characteristics of chemical resistance, it has been widely used as a sealing material and filling material. The dispersion can be used as an insulating immersion liquid for various materials and as an anti-corrosion coating on the surface of metal, glass and pottery. All kinds of PTFE ring, PTFE gasket, PTFE packing, etc. are widely used in all kinds of anti-corrosion pipeline flange sealing. In addition, it can also be used for spinning, PTFE fiber-Fluoron (foreign trade name is Teflon).
2. PTFE high temperature sleeve
PTFE high temperature casing has excellent comprehensive performance, high temperature resistance, corrosion resistance, non-stick, self-lubricating, excellent dielectric properties, low coefficient of friction.
PTFE high temperature casing used as engineering plastics, can be made of PTFE tube, rod, belt, plate, film, etc., generally used in high performance requirements of corrosion-resistant pipes, containers, pumps, valves and radar, high frequency communication equipment, radio equipment.
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. Filled with varieties of glass fiber, metal, metal oxide, graphite, molybdenum disulfide, carbon fiber, polyimide, EKONOL, etc., wear resistance, limit PV value can be increased by 1000 times.
PTFE high-temperature sleeves can be molded by compression or extrusion; they can also be made into aqueous dispersions for coating, impregnation or fiber making. PTFE in atomic energy, national defense, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, metal surface treatment, pharmaceutical, medical, textile, food, metallurgy and other industries are widely used as high and low temperature resistant, corrosion resistant materials, insulation materials, anti-stick coating, making it an irreplaceable product.

The mechanical properties of Ptfe high temperature bushings are relatively soft. Has very low surface properties.
High temperature resistance: long-term use temperature 200~260 degrees;
Low temperature resistance: still soft at -100 degrees;
Corrosion resistance: able to aqua regia and all organic solvents;
Weather resistance: the best aging life in plastics;
High lubrication: with the smallest coefficient of friction in plastics (0.04);
Non-stickiness: has the smallest surface tension in solid materials without adhering to any substance;
Non-toxic: physiologically inert; excellent electrical performance, is the ideal C- class insulation material.
