Properties of Polytetrafluoroethylene

• Non-Stick: PTFE has a very low coefficient of friction, which makes it repel other materials and prevents sticking.
• Chemical Resistance: It is highly resistant to most chemicals, including acids, bases, and solvents.
• Heat Resistance: PTFE can withstand high temperatures without degrading, making it suitable for use in cooking and industrial applications.
• Electrical Insulation: It is an excellent insulator and is used in electrical applications to prevent current leakage.
• Low Friction: PTFE has a low friction coefficient, which makes it ideal for applications where smooth movement is required.

Uses of Polytetrafluoroethylene

• Cookware and bakeware coatings
• Industrial piping and gaskets
• Electrical insulation
• Medical implants and devices
• Seals and gaskets in mechanical systems
• Non-stick coatings for machinery and equipment
