• Description: Poly-(Tetrafluoroethylene) (PTFE, Brand name: Teflon, Fluon, Hostaflon, and Polyflon) is a kind of strong, tough, waxy and nonflammable synthetic resin. Its structure formula is [CF2-CF2]n with a carbon backbone chain. It is produced through the free-radical polymerization of tetrafluoroethylene. PTFE has slippery surface, high melting point, and is extremely chemically inert. This property make it have a lot of applications. Its biggest application is for the wiring in aerospace and computer applications due to its excellent dielectric properties, e.g. as the insulator in cables and connector. In industry, PTFE can be applied in places where sliding action of parts is required due to its low friction such as plain bearings, gears and slide plates. PTFE is also applied in the production of carbon fiber composites and fiberglass composites. In addition, owing to its chemical inertia and high thermal resistance, PTFE is applied in places where acids, alkalis or other chemical are used, e.g. as the liner in industrial pipe lines. Tetrafl uoroethylene (TFE), also known as perfl uoroethylene, is a colorless, fl ammable, toxic gas. It is the monomer used for polytetrafl uoroethylene (PTFE), which is sold under the DuPont tradename of Tefl on. TFE is co-polymerized with other compounds to produce a variety of Tefl ons. TFE is produced by heating chlorodifl uoromethane (CHClF2, Freon-22) or trifl uoromethane (CHF3, Freon-23). TFE is used almost exclusively as a monomer in the production of PTFE. PTFE is a vinyl polymer, which means it is made from a monomer with carbon-carbon double bonds. PTFE is made from TFE by free radical polymerization.PTFE’s unique physical properties are due to its chemical structure. PTFE consists of long chains of carbon atoms surrounded by fluorine atoms. The fluorine atoms act as a protective barrier that shields the carbon-carbon bond from chemical attack. The fluorine atoms repel other atoms, making it diffi cult for anything to stick to PTFE. PTFE resins have very low coeffi cients of friction (< 0.1). The strong fluorine-to-carbon bonds and high electronegativity of fluorine make PTFE very stable. The long chains of PTFE pack closely together to give a dense crystalline solid. The packing, which can be compared to stacking boards, produces little cross-linking.
• Uses: Poly(tetrafluoroethylene) is used in hundreds of applications in addition to cookware. Poly(tetrafluoroethylene) is used in inks, plastics, coatings, and lubricants.Poly(tetrafluoroethylene) can be molded into gaskets, seals, bearings, gears, and other machine parts. Poly(tetrafluoroethylene) is used as liners, insulation, membranes, and adhesives. Tefl on tape is commonly used in plumbing work. Poly(tetrafluoroethylene) is used to produce rainproof garments. Inert lubricant. polytetrafluoroethylene powder be used for plastic modification, average particle size is about 3-5 and 10-20 micrometer, PTFE has excellent performance, it has unique properties, including, no self-coagulation, no electrostatic effect, good intermiscibility, low molecular weight, good dispersion, high self-lubrication, low friction coefficient, etc. For hookup and hookup-type wire in electronic equipment; in computer wire, electrical tape, electrical components, spaghetti tubing. Seals and piston rings, basic shapes, bearings, mechanical tapes, coated glass fabrics. As tubing and sheets for chemical laboratory and process work; for lining reaction vessels; for gaskets and pump packings, sometimes mixed with graphite or glass fibers; as electrical insulator especially in high frequency applications; filtration fabrics; protective clothing. Prosthetic aid. PTFE (polytetrafluoroethylene) is a bulking agent, it is also used in cosmetic preparations to improve the formulation’s feel and spreadability. PTFe may also have some waterproofing potential.
