What is telfon?
Teflon is a name that was trademarked for a group of fluoropolymer products.
What many people don’t know, however, is that when they request a Teflon product, there is actually a full family of products available under that heading. Resins that possess the same, similar, or in some cases, even superior properties, include PTFE, FEP, PFA, HP PFA, and UHP PFA resins.
How was Teflon first produced?
In 1938, a man by the name of Dr Roy Plunkett was working on a project to develop refrigerants. In doing so, he discovered a by-product that proved to be inert to most chemicals. The product was named polytetrafluoroethylene — the material we now commonly call PTFE.
In 1944, the name Teflon was trade-marked for the material, and by the mid 1950s, a number of PTFE resins were released for the commercial market, particularly for use in pipe and tubes. Further research led to the development of new forms of Teflon over the years — including FEP, PFA, and HP PFA.
Nowadays, an organisation known as The Chemours Company is in possession of the Teflon brand. There are, however, a number of other companies who produce the same materials. The only difference? They are not labelled under the Teflon brand name.
Do we offer Teflon products?
At Altaflo, we don’t offer any of the Teflon products, or other Chemours resins, because these products are only licensed by Chemours to use the trade-marked name. That said, we offer a range of fluoropolymer resins that have similar, and often identical, properties.
This was the original Teflon material that was developed. Our PTFE tubing is the most flexible material of its kind. It has the broadest temperature range of any fluoropolymer and can resist highly corrosive liquids and gases even at very elevated temperatures. Our PTFE tubing can be used in a number of applications, including laboratory and chemical processes; analytical and process equipment; emissions monitoring; cryogenic applications; high temperatures applications; electrical applications; automotive paint spray; as well as automotive push-pull cables and hose assemblies.

PFA is often the tubing of choice when it comes to applications that involve extreme chemical resistance and high temperature exposure. The PFA tubing and pipe that we offer is made from the highest molecular weight resins currently available, which gives them superior physical qualities — they have higher thermal stability and lower permeability than FEP, for example.

Our HP PFA products are used widely in a number of industries, including semiconductor, automotive, chemical, petrochemical and pharmaceutical, as well as the food and medical industries. Products made from this material are unique in that they resist ignition and do not promote flame spread. When ignited by flame and other sources, their contribution of heat is very small and added at a slow rate, with very little smoke. For this reason, HP PFA is ideal for situations that require low flammability, as well as performance at temperature extremes. The material also has excellent weather resistance.
