The sealing industry is full of trade names, technical phrases, and acronyms, which makes it hard to know what is what. In this learning journal, we will explain what Teflon™ and PTFE are, and also the differences.
PTFE is a carbon and fluorine synthetic polymer – Polytetrafluoroethylene. It is obtained from Tetrafluoroethylene (TFE) and presents a number of very distinctive characteristics that make it very functional and practical for use in a wide range of applications. These include:
Some applications, in which you can find Teflon:
This shows that all the exceptional characteristics of PTFE make it very useful and widely used in commercial as well as domestic applications.
Examples of the most demanding PTFE applications:
Teflon™ was discovered in 1938, developed by DuPont Co, and administered by Chemours. In 1045 Chemours trademarked the name Teflon™, and in 1946 they started selling products coated in this heatproof and non-stick material. Teflon™ was discovered by scientist Dr. Roy Plunkett as he worked on developing a new refrigerant. He then noticed that the TFE gas has escaped from the bottle he was using; however, the bottle hasn’t lost its weight and did not feel empty. Therefore, to find out the cause of this phenomenon, he examined the inside of the bottle and noticed it was covered in a slippery, strong, and waxy material – it was Teflon.
Teflon™ is a synthetic polymer, which is containing carbon and fluorine – this, therefore, makes it Polytetrafluoroethylene. YES, Teflon™ is a PTFE. Teflon™ is a trademarked name for PTFE, owned by Chemours.
There is NO DIFFERENCE. They are both exactly the same thing, the only difference between them is the name.
