Polytetrafluoroethylene, also known as Teflon®, is made with four ingredients -- fluorspar, hydrofluoric acid, chloroform, and water, which are combined in a chemical reaction chamber heated to between 1094-1652°F (590-900°C). Creating PTFE involves 2 main phases and a series of reactions.

What exactly is it? PTFE (polytetrafluorethylene) is a polymer that we, at T-fal, were the first to use for the coatings of our non-stick pans.

The modern non-stick pans were made using a coating of Teflon (polytetrafluoroethylene or PTFE). PTFE was invented serendipitously by Roy Plunkett in 1938, while working for a joint venture of the DuPont company.

Teflon, a famous brand of material used to create nonstick cookware is derived from polytetrafluoroethylene (PTFE), part of the family of PFAS chemicals. 'Glide' flosses are also made using PTFE.

['Reasonably fast prototyping and production time frames.', 'Ability to create large parts (up to 48 inches x 96 inches)', 'Lower start-up costs — patterns and moulds can be made economically from MDF, high density foams and epoxy.']

Teflon is the brand name for a plastic product called polytetrafluoroethylene (PTFE). PFOA (Perfluorooctanoic Acid) is another chemical that is used in the process of making PTFE. It is NOT the same as PTFE. PFOA is burned off during the process and no significant amount remains in the final product.

Polytetrafluoroethylene, better known as Teflon, is a synthetic fluoropolymer. A synthetic fluoropolymer is a fluorocarbon-based polymer with multiple strong carbon-fluorine bonds, making it highly resistant to solvents, acids and bases.

Most non-stick pans, including the famous Tefal pans, are coated in a material called polytetrafluorethylene (PTFE), which is also known as Teflon. It is a chemical made of carbon and fluoride, which sounds toxic, but is actually a very stable molecule.

PTFE stands for PolyTetraFluoroEthylene, which is the chemical term for the polymer (CF2)n. Polytetrafluoroethylene (PTFE) is a thermoplastic member of the fluoropolymer family of plastics and has a low coefficient of friction, excellent insulating properties.

A spokesman for Tefal, said: ”Tefal pans have a non-stick coating that is made from an inert substance called polytetrafluoroethylene (PTFE), which is totally harmless in the rare case of ingestion.

PFOA, PTFE and the Differences between the Two PFOA, short for perfluorooctanoic acid, is a synthetic compound that has many applications. It is known to repel water and oil and is used in the manufacturing process of some PTFE cookware. PTFE, a distinct substance, is a synthetic polymer.

They are made of PTFE which is more known as Teflon. Due to the low friction, great glide is achieved on all surfaces. The other major advantage is sustainability.

Due to the fluorine atoms surrounding the carbon and its tight structure, teflon is chemically inert, because almost nothing can react with the carbon and the tight bonding of C-F bonds, also on top of that, PTFE is extremely heavy, its molecular weight exceeding 30,000 Daltons and is packed tightly.
