Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia. It can be stretched to contain small pores of varying sizes and is then placed between fabric layers to make a waterproof, breathable fabric in outdoor apparel. It is a fluoropolymer, because the polymerization is based on strong bonds of fluorine and carbon. Teflon is also called polytetrafluoroethylene, meaning it only consists of carbon and fluorine, whereas the cyanide ion is made of carbon and nitrogen. Unique properties of PTFE include nonreactivity, hydrophobicity, a low coefficient of friction, and good insulating properties. PTFE is produced by free-radical polymerization of tetrafluoroethylene. [18] At temperatures above 650–700 °C (1,200–1,290 °F) PTFE undergoes depolymerization.[19]. He subsequently created the first PTFE-coated, non-stick pans under the brand name Tefal (combining "Tef" from "Teflon" and "al" from aluminum). One of the common applications of this polymer is non-stick coating in kitchen cookware (pans, baking trays etc. Polytetrafluoroethylenes are thermoplastic polymers made from the monomer tetrafluoroethylene (CF 2 =CF 2 ). In its first form, polytetrafluoroethylene is a touch, waxy, synthetic resin. Its frictionless qualities allow improved flow of highly viscous liquids, and for uses in applications such as brake hoses. Another popular brand name of PTFE is Syncolon by Synco Chemical Corporation. The particular combination of these two chemical elements arranged along the molecular chain imparts a unique set of properties to these types of carbon - fluorine based polymers. Since Plunkett was measuring the amount of gas used by weighing the bottle, he became curious as to the source of the weight, and finally resorted to sawing the bottle apart. [2] Chemours was a spin-off from DuPont, which originally discovered the compound in 1938. Polytetrafluoroethylene is not very reactive. Home; Test Lab Permeation. Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene. Because of its chemical inertness, PTFE cannot be cross-linked like an elastomer. innovation for your business. [25] PTFE's coefficient of friction is 0.05 to 0.10,[16] which is the third-lowest of any known solid material (BAM being the first, with a coefficient of friction of 0.02; diamond-like carbon being second-lowest at 0.05). PTFE is a fluorocarbon solid, as it is a high molecular weight compound consisting wholly of carbon and fluorine. [11] Non-stick cookware has since become a common household product, now offered by hundreds of manufacturers across the world. hookup wire, coaxial cables). Tetrafluoroethylene or TFE molecule , is a monomer of Polytetrafluoroethylene or PTFE. It is better known by its trade-names, Teflon, and Gore … Abbreviation: PTFE Also called (trademark): Teflon. Because PTFE is poorly soluble in almost all solvents, the polymerization is conducted as an emulsion in water. [14] The net equation is. ", Plasma Processes and Adhesive Bonding of Polytetrafluoroethylene, PTFE (polytetrafluoroethylene) (Properties) | Fluorotherm.com, https://en.wikipedia.org/w/index.php?title=Polytetrafluoroethylene&oldid=1001972834, Short description is different from Wikidata, Chemicals that do not have a ChemSpider ID assigned, Articles containing unverified chemical infoboxes, Articles lacking reliable references from September 2020, Articles needing additional references from May 2017, All articles needing additional references, All articles that may have off-topic sections, Wikipedia articles that may have off-topic sections from December 2020, Creative Commons Attribution-ShareAlike License, It is often found in ski bindings as a non-mechanical AFD (anti-friction device). [3][promotional source?]. RM Products is gespecialiseerd in het toeleveren van kunststof materialen zoals PTFE. Traditional non-stick cooking pans use a coating called polytetrafluoroethylene that cannot withstand overheating.. undefined. As a result of a class-action lawsuit and community settlement with DuPont, three epidemiologists conducted studies on the population surrounding a chemical plant that was exposed to PFOA at levels greater than in the general population. That’s right, Teflon is PTFE but by another name. PTFE-coated filters are often used in, Many bicycle lubricants and greases contain PTFE and are used on, PTFE sheets are used in the production of, PTFE, associated with a slightly textured laminate, makes the plain bearing system of a. PTFE is widely used as a non-stick coating for food processing equipment; PTFE is commonly used in aftermarket add-on mouse feet for, PTFE foils are commonly used with laserprinters everywhere, in their fuser unit, wrapped around the heater element(s) and as well on the opposite pressure roller to prevent any kind of sticking to it (neither the printed paper nor toner waste). Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The PTFE, used here as a film, prevents the non-production materials from sticking to the part being built, which is sticky due to the carbon-graphite or fiberglass plies being pre-pregnated with bismaleimide resin. [32] After a settling period, lasting from minutes to days, the mould is heated at 360 to 380 °C (680 to 716 °F),[32] allowing the fine particles to fuse into a single mass.[33]. PTFE tubes are used in gas-gas heat exchangers in gas cleaning of waste incinerators. Like normal polytetrafluoroethylene, ePTFE is highly heat-resistant and hydrophobic, but it is also easy to shape into a thin, fabric-like material that can be deployed in many more applications than traditional PTFE, which is more rigid. Polytetrafluoroethylene tube is also called PTFE Tube, commonly known as “Plastic King”, is a high molecular polymer prepared by polymerizing tetrafluoroethylene as a monomer. For other uses, see, Syncolon, Fluon, Poly(tetrafluroethene), Poly(difluoromethylene), Poly(tetrafluoroethylene), teflon, Except where otherwise noted, data are given for materials in their, Carlson, D. Peter and Schmiegel, Walter (2000) "Fluoropolymers, Organic" in, "From stove tops to outer space... Teflon touches every one of us some way almost every day. The best kent brand name o PTFE-based formulas is … polytetrafluoroethylene (PTFE), a strong, tough, waxy, nonflammable synthetic resin produced by the polymerization of tetrafluoroethylene. This process gives a suspension of polymer particles. Polytetrafluoroethylene. Compare Products: Select up to 4 products. ), hence, you can easily find this in your kitchen. TFE is also used in the preparation of numerous copolymers that also include hydrogen and/or oxygen, including both fluoroplastics and fluoroelastomers. In the 1990s, it was found that PTFE could be radiation cross-linked above its melting point in an oxygen-free environment. It is notable for its extremely low coefficient of friction, its hydrophobia (which serves to inhibit rust), and for the dry film it forms after application, which allows it to resist collecting particles that might otherwise form an abrasive paste.
