What is PTFE?

Poly tetrafluoroethylene, abbreviated as PTFE, Teflon, it is a polymer compound formed by the polymerization of tetrafluoroethylene. Its simple structure is-[-CF2-CF2-] n-, which has excellent chemical stability and corrosion resistance. It is one of the best materials with corrosion resistance in the world today. Except for molten alkali metal, chlorine trifluoride, chlorine pentafluoride, and liquid fluorine, it is resistant to all other chemicals. It is used in various occasions that need to resist acid and alkali and organic solvents. It has tightness, high lubricity and non-stickiness, electrical insulation, good aging resistance, and excellent temperature resistance.

Is PTFE safe?

PTFE itself is not toxic to humans and can be used in medical and health applications. The yarn made of PTFE is pure inert, non-toxic, has extreme biological adaptability, does not cause rejection of the body, has no physiological side effects on the human body, can be sterilized by any method, and has a microporous structure so that it can be used. Artificial blood vessels for tissue regeneration, and surgical sutures for vascular, cardiac, general, and plastic surgery. Its excellent anti-microbial, antibacterial, long flex life and zero moisture regain, etc., make people continue to open up the application of fibers in this field. In recent years, PTFE yarns have also been used as abrasion-resistant materials for wear-resistant clothing.

Uses of Teflon and PTFE properties

The production of PTFE has solved many problems in chemical, petroleum, pharmaceutical, and other fields. Teflon seals, gaskets, and gaskets. Teflon seals, gaskets, and gaskets are molded from suspension polymerized polytetrafluoroethylene resin. Compared with other plastics, PTFE has the characteristics of chemical resistance, and it has been used as a sealing material. The dispersion liquid can be used as an insulating impregnating solution for various materials and an anti-corrosive coating on the surface of metal, glass, and ceramics. Different PTFE rings, PTFE gaskets, PTFE packings, etc. are widely used for sealing flanges of different anti-corrosive pipes.

Nowadays, all kinds of PTFE products have played a pivotal role in the national economic fields such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection, and bridges. PTFE use conditions industry chemical, petrochemical, oil refining, Chlor-alkali, acid production, phosphate fertilizer, pharmaceuticals, pesticides, chemical fiber, dyeing, cooking, gas, organic synthesis, non-ferrous smelting, steel, nuclear energy and polymer filter materials, high-purity product production (Such as ion membrane electrolysis), viscous materials transportation and operation, food and beverage processing and production departments with strict hygiene requirements.

PTFE lubricant

PTFE fiber has a very low coefficient of friction. It is made of fabric self-lubricating pads by weaving and impregnating resins such as phenolic resin and epoxy resin. During heavy-duty wear, a PTFE transfer film is formed between the inner and outer ring contact surfaces of the spherical plain bearing, thereby significantly reducing the friction coefficient between the inner and outer races of the bearing, and extending the service life of the self-lubricating spherical plain bearing. Plain bearings with PTFE fiber or fabric have the characteristics of lubrication-free, durable, and good environmental adaptability. They have been used in the industrial field of bearings with a heavy load, maintenance-free, small size, and lightweight. PTFE fiber bearings are used in food processing machinery to ensure food hygiene to a large extent and eliminate lubricant pollution.
