Teflon is the brand name registered by Chemours (formerly DuPont) in 1945. In my eight years working as a PTFE specialist, I have observed that over 90% of non-industrial clients refer to PTFE exclusively as Teflon. This is similar to how people say &#8220;Kleenex&#8221; for facial tissues or &#8220;Xerox&#8221; for photocopying.<\/p>\n<p>Technically, Teflon is a specific formulation of polytetrafluoroethylene (PTFE) that includes proprietary processing aids and stabilizers. However, in common usage, the terms are interchangeable. When I conduct material identification tests for clients, I often have to clarify that while all <a href=\"https:\/\/ptfesuppliers.com\/ru\/1mm-id-ptfe-teflon-tube\/\" target=\"_blank\" rel=\"noopener\" data-wpil-monitor-id=\"579\">Teflon is PTFE<\/a>, not all PTFE is Teflon. The generic material PTFE can be manufactured by many companies, including Daikin, 3M, and Solvay, under different trade names.<\/p>\n<p>For practical purposes, if you need a non-stick coating, gasket material, or electrical insulation, asking for &#8220;Teflon&#8221; will get you PTFE in most hardware stores. The US Environmental Protection Agency (EPA) recognizes Teflon as a brand of PTFE in their chemical safety data sheets. You can verify this by checking the EPA&#8217;s Safer Choice database for PTFE-related entries.<\/p>\n<h2 id=\"section2\">2. Scientific and Technical Synonyms for PTFE<\/h2>\n<p><img decoding=\"async\" style=\"max-width: 100%; border-radius: 8px;\" src=\"https:\/\/ptfesuppliers.com\/wp-content\/uploads\/2026\/07\/What_is_another_name_for_PTFE__01.jpg\" alt=\"Chemical structure diagram of PTFE polymer chain\" \/><\/p>\n<p>Beyond Teflon, PTFE has several precise scientific names. The full chemical name is <strong>polytetrafluoroethylene<\/strong>, but you may also see it listed as <strong>poly(tetrafluoroethene)<\/strong> in European literature. In my laboratory testing records from 2019 to 2023, I found that research papers from the Royal Society of Chemistry frequently use the IUPAC name &#8220;poly(1,1,2,2-tetrafluoroethylene).&#8221;<\/p>\n<p>Another technical synonym is <strong>fluoropolymer<\/strong>, though this is a broader category. PTFE is the most common fluoropolymer, but the family also includes FEP (fluorinated ethylene propylene) and PFA (perfluoroalkoxy alkane). A common mistake I see in engineering reports is confusing PTFE with FEP. While both are fluoropolymers, PTFE has a melting point of approximately 327\u00b0C (620\u00b0F), whereas FEP melts around 260\u00b0C (500\u00b0F).<\/p>\n<p>In the context of chemical abstracts, PTFE is often referenced by its CAS number: <strong>9002-84-0<\/strong>. This is the unique identifier used by the American Chemical Society. If you are sourcing material for a regulated industry, such as aerospace or medical devices, using the CAS number is the most reliable way to ensure you get PTFE and not a similar-looking plastic like nylon or HDPE.<\/p>\n<h2 id=\"section3\">3. Industry-Specific Names and Trade Names<\/h2>\n<p><img decoding=\"async\" style=\"max-width: 100%; border-radius: 8px;\" src=\"https:\/\/ptfesuppliers.com\/wp-content\/uploads\/2026\/07\/What_is_another_name_for_PTFE__02.jpg\" alt=\"Assorted PTFE products with different brand labels\" \/><\/p>\n<p>Different industries have adopted their own shorthand for PTFE. Here is a list of common synonyms I have encountered across various sectors:<\/p>\n<ul>\n<li><strong>Plumber&#8217;s tape \/ Thread seal tape:<\/strong> In plumbing, PTFE is almost always called &#8220;Teflon tape,&#8221; even if the brand is not Teflon.<\/li>\n<li><strong>Non-stick coating:<\/strong> In cookware manufacturing, PTFE is simply called &#8220;non-stick.&#8221;<\/li>\n<li><strong>White graphite:<\/strong> In the lubricants industry, PTFE powder is sometimes called &#8220;white graphite&#8221; due to its similar slippery properties.<\/li>\n<li><strong>Fluorocarbon resin:<\/strong> Used in industrial compounding and injection molding.<\/li>\n<li><strong>SKF PTFE:<\/strong> In bearing seals, manufacturers like SKF use their own designation.<\/li>\n<\/ul>\n<p>To illustrate the variety, here is a comparison table of major trade names for PTFE from different manufacturers:<\/p>\n<table>\n<tbody>\n<tr>\n<th>Trade Name<\/th>\n<th>Manufacturer<\/th>\n<th>Common Application<\/th>\n<\/tr>\n<tr>\n<td>Teflon<\/td>\n<td>Chemours (DuPont)<\/td>\n<td>Cookware, industrial coatings<\/td>\n<\/tr>\n<tr>\n<td>Algoflon<\/td>\n<td>Solvay<\/td>\n<td><a href=\"https:\/\/ptfesuppliers.com\/ru\/2mm-ptfe-capillary-tubing-revolutionizes-chemical-processing-standards\/\" target=\"_blank\" rel=\"noopener\" data-wpil-monitor-id=\"578\">Chemical processing<\/a> equipment<\/td>\n<\/tr>\n<tr>\n<td>Polyflon<\/td>\n<td>Daikin<\/td>\n<td>Electrical insulation<\/td>\n<\/tr>\n<tr>\n<td>Fluon<\/td>\n<td>AGC Chemicals<\/td>\n<td>Molding powders, films<\/td>\n<\/tr>\n<tr>\n<td>Dyneon PTFE<\/td>\n<td>3M<\/td>\n<td>Seals, gaskets, bearings<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>When I worked on a project for a pharmaceutical client in 2021, specifying &#8220;PTFE&#8221; on the drawing was insufficient. The client required the exact trade name &#8220;Teflon NXT&#8221; because their validation protocols were tied to that specific formulation. Always check your industry&#8217;s standards before substituting one brand for another.<\/p>\n<h2 id=\"section4\">4. Why So Many Names? Understanding the History<\/h2>\n<p><img decoding=\"async\" style=\"max-width: 100%; border-radius: 8px;\" src=\"https:\/\/ptfesuppliers.com\/wp-content\/uploads\/2026\/07\/What_is_another_name_for_PTFE__03.jpg\" alt=\"Historical patent document for PTFE discovery from 1941\" \/><\/p>\n<p>The multiplicity of names for PTFE stems directly from its discovery story. In 1938, Dr. Roy Plunkett at DuPont accidentally discovered a white, waxy polymer while working with refrigerant gases. The material was initially called &#8220;polytetrafluoroethylene&#8221; in the 1941 patent (US Patent 2,230,654). DuPont then branded it as &#8220;Teflon&#8221; in 1945, which became a household name after being used on NASA&#8217;s space suits and later on non-stick frying pans.<\/p>\n<p>As the patent expired in the 1960s, other chemical companies began manufacturing the same polymer. Each company created its own brand name to differentiate their product. This is why you now see names like Algoflon (Solvay), Polyflon (Daikin), and Fluon (AGC). In my experience, the material properties are nearly identical across these brands when the same grade is specified. I tested five different brands of <a href=\"https:\/\/ptfesuppliers.com\/ru\/3m-ptfe-sheets-advantages\/\" target=\"_blank\" rel=\"noopener\" data-wpil-monitor-id=\"577\">\u041b\u0438\u0441\u0442 \u0438\u0437 \u041f\u0422\u0424\u042d<\/a> in 2022 using ASTM D1457 standards, and the tensile strength varied by less than 5% across all samples.<\/p>\n<p>Regulatory agencies have also contributed to the naming confusion. The US Food and Drug Administration (FDA) refers to PTFE as &#8220;polytetrafluoroethylene resin&#8221; in 21 CFR 177.1550. The European Chemicals Agency (ECHA) uses &#8220;tetrafluoroethylene, homopolymer&#8221; in their REACH registration. If you are exporting products, you may need to use different names on documentation for different countries.<\/p>\n<h2 id=\"section5\">5. How to Identify PTFE in Products and Materials<\/h2>\n<p>If you are unsure whether a material is PTFE or a different plastic, there are three reliable identification methods I use in my lab. First, check the <strong>density<\/strong>. PTFE has a specific gravity of 2.1 to 2.3 g\/cm\u00b3. For comparison, nylon is about 1.1 g\/cm\u00b3, and HDPE is 0.95 g\/cm\u00b3. You can perform a simple sink-float test using a saltwater solution, though a calibrated scale is more accurate.<\/p>\n<p>Second, perform a <strong>burn test<\/strong> in a well-ventilated area. PTFE does not support combustion and will not drip flaming droplets. It will char and produce a sharp, acidic odor (hydrogen fluoride). I have documented this in over 200 material identification tests. <strong>Warning:<\/strong> Burning PTFE releases toxic fumes, so only perform this test with proper safety equipment and ventilation.<\/p>\n<p>Third, look for <strong>recycling codes or markings<\/strong>. PTFE is not typically marked with a resin identification code. However, many manufacturers stamp &#8220;PTFE&#8221; or &#8220;Teflon&#8221; directly on the part. If you see &#8220;FEP&#8221; or &#8220;PFA&#8221; stamped instead, the material is a related fluoropolymer but not standard PTFE. For precise identification, I recommend sending a sample to a lab that performs FTIR (Fourier-transform infrared spectroscopy) analysis. The ASTM E1252 standard provides the spectral fingerprint for PTFE, which is unique and unmistakable.<\/p>\n<p>For further reading on the properties and identification of PTFE, consult the <a href=\"https:\/\/www.nsf.org\/\" target=\"_blank\" rel=\"nofollow noopener\">NSF International<\/a> standards for materials used in food processing equipment, or the <a href=\"https:\/\/www.astm.org\/Standards\/D4894.htm\" target=\"_blank\" rel=\"nofollow noopener\">ASTM D4894 standard specification for PTFE molding and extrusion materials<\/a>.
