What is Teflon®?

Teflon® is a registered trademark of DuPont and is used in all the fluorocarbon resin products that it manufactures.

What is PTFE?

Polytetrafluoroethylene or PTFE is the chemical name given to the equation (-CF2-CF2-)n.

Polytetrafluoroethylene or PTFE (Teflon®, registered trademark of DuPont) is a thermoplastic polymer with low coefficient of friction, outstanding insulation properties and it is also chemically inert to most of the substances. PTFE has a great resistance to high temperatures and it is well-known for its anti-stick properties.

There are different PTFE registered trademarks (besides Teflon® by DuPont).  Those include:

Fluon® is a registered trademark of AGC Chemicals Americas, Inc. (AGC). Its facilities are located in England and Japan.

Dyneon®  is a registered trademark of 3M Company, it produces PTFE resin in Gendorf, Germany.

Polyflon® is a registered trademark of Daikin Industries LTD. It is located in USA, Japan and China.

Algoflon® is a registered trademark of Solvay Solexis, and their facilities are in USA and Italy.

Fluoroplast® is a registered trademark of Kirovo-Chepetsky. They are located in Perm and Kirovo-Chepetsky, Russia.

Inoflon® is a registered trademark of Gujarat Fluorochemicals Limited, which is located in Gujarat, India.

PTFE HISTORY

PTFE History

Teflon history began on April 6TH, 1938 in DuPont Labs, located in New Jersey, USA.

Dr. Roy J. Plunkett, who was working with Freon gases, accidentally discovered that a sample he had left the night before in a pressure bottle, was polymerized into a waxy white material.

An analysis showed that it had outstanding properties and it was also very resistant to almost all chemicals and solvents; its surface was extremely slippery and as a result, nothing could stick on it. It was shown, as well, that this material didn’t absorb any moisture itself; sunlight could not degrade it and its melting point was at 620°F (342°C). However, the resin does not flow above the melting point, in contrast to common thermoplastics. As a result it could not be processes using the same method, so they developed a new one: compression molding to ambient conditions. They made this new material into bars and tubes that could be machined in different parts, followed by the disperse water resin which could be used in fiberglass fabrics; making it a PTFE coating.

DuPont made PTFE available for the market in 1948, when the first companies started to distribute this product that we currently process it in our company, based in Toluca.
