PTFE (polytetrafluoroethylene) is a polymer compound made by polymerizing tetrafluoroethylene (TFE) with many unique properties and a wide range of applications. PTFE is a high-performance semi-crystalline fluoropolymer known for its excellent chemical resistance, thermal stability and non-stick properties. This unique combination of attributes has led to its widespread application in diverse industries, from aerospace and automotive to cookware and medical devices.

Characteristics of PTFE

• Chemical Resistance: PTFE is resistant to almost all chemicals and does not react with any chemicals except chlorine trifluoride, elemental fluorine and molten alkali metals. This makes it ideal for use in corrosive environments.
• Thermal Stability: PTFE can remain stable at temperatures up to 260°C without significant decomposition.
• Non-stick Properties: The low surface energy of PTFE results in its well-known non-stick properties, making it a popular choice for cookware and other applications where non-adhesion is crucial.
• Electrical Insulation: PTFE is an excellent electrical insulator, making it suitable for use in the insulation layer of electrical and electronic components.
• Low Friction: PTFE has a very low coefficient of friction, usually between 0.05 and 0.10, which makes it an ideal lubricating material and is widely used in mechanical parts and anti-stick coatings.
