PTFE

PTFE, or polytetrafluoroethylene as it is otherwise known, is a synthetic fluoropolymer of tetrafluoroethylene. It is an incredibly versatile material with a wide range of applications that is best known for its non-stick properties, commonly sold under the trademark of Teflon™.

Characteristics of PTFE

PTFE is most commonly known for its friction resistance and non-stick properties but it also has many other characteristic that make it useful in a range of applications and industries. PTFE has exceptional resistance to harsh chemicals, extreme temperatures and weathering. It is reportedly able to withstand temperature ranging from -200°C up to +300°C. It has excellent electrical insulation properties and it does not show signs of ageing or becoming brittle.

Applications of PTFE

The resistance to harsh chemicals means that PTFE sees a lot of use in the chemical synthesising industry. It is used in metallic hose assemblies for the transfer of chemicals, acids, solvents and detergents. PTFE is also excellent at resisting friction. It is widely used across the medical and clothing industry as a coating for high friction areas of footwear, insoles, and pressure sensitive medical tapes called PTFE tape. You may know PTFE as a coating for non-stick frying pans due to its thermal stability and non-stick properties, commonly called Teflon™.

Our Expanded PTFE Sealing tape or sheets are approved food grade, they have excellent resistance to a wide range of chemicals and they are extremely compressible. The tape format has been specifically designed to replace full gaskets. They are most effective when slightly overlapping the tape around the sealing face. A seal is created by bolting one flange to another, and the soft flexible nature of this material provides a seal on standard and even irregular or defective areas.
