Buy Polytetrafluoroethylene (PTFE) With Confidence

What is polytetrafluoroethylene?

Polytetrafluoroethylene (PTFE) is a strong, tough, waxy synthetic resin produced by the polymerisation of tetrafluoroethylene (TFE) monomers. The polymer chain consists of carbon atoms each bonded to two fluorine atoms (–CF₂–CF₂–)n, creating a protective sheath that makes the molecule chemically inert, water‑repellent and resistant to heat. PTFE is better known by trademarks such as Teflon®, Fluon®, Hostaflon® and Polyflon®. The material has a semi‑crystalline structure and the lowest known coefficient of friction among solids. Its chemical name is polytetrafluoroethylene and its CAS number is 9002‑84‑0.

The resin was discovered accidentally on 6 April 1938 by DuPont chemist Roy J. Plunkett. While attempting to develop a new refrigerant, Plunkett noticed that a cylinder of TFE gas had stopped flowing despite retaining weight. He opened it and found a slippery white powder—polymerised PTFE. DuPont patented the material in 1941 and registered the Teflon trademark in 1945. During World War II, PTFE was used to coat valves and seals for handling uranium hexafluoride in the Manhattan Project. Commercial success came later; non‑stick frying pans were first marketed in France in the late 1950s and in the United States by 1961.

Structure and key properties

PTFE owes its unique performance to strong carbon–fluorine bonds. Key physical properties include:

Other characteristics include hydrophobicity—water droplets bead on PTFE surfaces—and resistance to UV radiation and most chemicals. Its coefficient of friction is so low that even geckos cannot stick to PTFE. These properties explain why PTFE is often used as a gasket, lubricant or non‑stick coating.

Manufacturing and forms

Polymerisation process

PTFE is produced via free‑radical polymerisation of tetrafluoroethylene. Because TFE can decompose explosively to carbon and tetrafluoromethane, polymerisation requires specialised high‑pressure equipment. Initiators such as persulfate generate sulphate radicals that start the chain reaction. Suspension polymerisation disperses the monomer as bubbles in water with peroxide initiators; the reaction occurs at ~30 bar and ~65 °C. PTFE grains form within the bubbles and agglomerate into granules as TFE is continuously added. The concentration of peroxide controls the polymer chain length and whether the product is a grease, wax or solid. Dispersion (emulsion) polymerisation produces finer particles but historically used surfactants like perfluorooctanoic acid (PFOA).

After polymerisation, the powder is sintered—heated at 360–380 °C while under pressure—to fuse particles into solid shapes. Granular PTFE is also produced through suspension polymerisation. Additives like glass fibres, carbon, bronze or stainless‑steel powders may be incorporated to improve strength or wear resistance.

Forms and commercial products

Because PTFE does not flow when molten and has high melt viscosity, fabricating parts requires special techniques such as compression moulding or paste extrusion. PTFE is available in a wide range of forms:

• Resins and powders: granular polytetrafluoroethylene resin and virgin polytetrafluoroethylene are used to mould rods, sheets, expanded polytetrafluoroethylene sheet, expanded PTFE membrane and fine powders for coatings.

• Film and sheet: thin polytetrafluoroethylene film, PTFE sheet and PTFE tape are used for gasketing, sealing, and insulation. PTFE thread seal tape is a ubiquitous plumbing product.

• Machined parts: PTFE rods, tubing, gaskets, o‑rings, washers, foils, board and panels. These parts provide low‑friction bearings, bushings and seals in industrial equipment.

• Coatings: PTFE‑based sprays, grease, lubricants and dry lubricants with polytetrafluoroethylene reduce friction in machinery. PTFE coatings are applied to non‑stick cookware, clothes irons, and industrial bakeware. They also protect bullets, pipes and medical devices from corrosion and wear.

• Laboratory ware: PTFE beakers, bottles, autoclaves, digestion bombs, hoses, liners and vessels provide inert containers for corrosive chemicals.

• Consumer products: PTFE clothing, gloves, jackets, floss and sutures, as well as PTFE‑coated fabrics (e.g., Gore‑Tex) for waterproof yet breathable clothing.

Uses and applications

The PTFE market is diversified because the material’s properties suit many industries. About half of global PTFE production goes into wire insulation and electronics. PTFE’s low dielectric constant and high melting point make it an ideal insulator for hook‑up wire, coaxial cables and microwave printed circuit boards. In industrial settings, PTFE’s low friction and chemical inertness make it useful for plain bearings, gears, slide plates, seals and bushings. PTFE composites are used as films in carbon‑fibre and glass‑fibre composites, particularly in aerospace, where they act as release films to prevent materials from sticking during curing.

PTFE’s extreme non‑reactivity allows it to line hoses, expansion joints and pipework that handle acids and bases. Architectural membranes coated with PTFE cover stadiums and large roofs because the material combines strength, durability and translucency. The well‑known Gore‑Tex brand uses expanded PTFE (ePTFE) as a microporous membrane for waterproof yet breathable fabrics. PTFE is also used in lubricants, musical instrument valve oil, ski bindings, medical devices, dental floss, laboratory filters, infrared decoy flares and even in 3D‑printer Bowden tubing. Powdered PTFE mixed with powdered aluminium or magnesium is an oxidiser in pyrotechnic compositions.

In medicine, PTFE’s biocompatibility enables vascular grafts, surgical meshes, dental membranes and drug‑delivery devices. Expanded PTFE membranes help in ocular surgery, and PTFE‑coated catheters and sutures reduce friction and tissue trauma. PTFE beakers, digestion bombs and autoclaves provide inert laboratory equipment, while PTFE coated bullets reduce wear on rifle barrels.

Non‑stick cookware and safety

PTFE’s most familiar use is non‑stick cookware. The coating’s hydrophobic and low‑friction properties allow cooking without sticking. PTFE remains stable at normal cooking temperatures but starts to degrade around 260 °C (500 °F) and decomposes above 350 °C (662 °F). Degradation releases fluorocarbon gases that can cause polymer‑fume fever in humans and are lethal to birds. Such high temperatures are unlikely with ordinary cooking—most oils smoke below 260 °C—yet overheated empty pans should be avoided. Historically, manufacturing PTFE coatings used perfluorooctanoic acid (PFOA) as an emulsion surfactant. The U.S. EPA’s 2010/2015 PFOA Stewardship Program asked eight major PFAS producers to reduce PFOA emissions by 95 % by 2010 and to eliminate them by 2015. Companies reported meeting these goals; PFOA manufacture and import have been phased out in the United States. Modern PTFE cookware therefore does not contain PFOA.
