Product Description

Product Description

Virgin PTFE sheet (often incorrectly referred to as Teflon™ sheet) is a high performance thermoplastic that offers very low moisture absorption, provides exceptionally low coefficient of friction has excellent dielectric strength. It is highly resistant to corrosion and hydrolysis, has a broad operating temperature and is chemically inert (with the exception of elemental alkali metals, chlorine trifluoride and elemental fluorine at high temperatures and pressures). PTFE sheet is also food approved and resistant to UV, but is subject to creep and is not suitable for use with highly abrasive materials.

Due to its characteristics, PTFE can be used to contain highly aggressive chemicals as a gasket, lining or bushing. The material can also be used as a slide plate or bearing in low friction applications and is suitable for use as an electrical insulator. If you are seeking to bond PTFE sheet with an adhesive, we can supply a chemically etched option that will adhere to materials such as metals, rubbers and other plastics. We also have the capability to machine PTFE to bespoke requirements from drawings or existing samples. For more information regarding the services we can provide, please visit our plastic machining section.
