PTFE (polytetrafluoroethylene), also known by its trade name Teflon, is a synthetic fluoropolymer with many applications: 

• Nonstick coating: PTFE is commonly used as a nonstick coating for cookware. 
• Electrical insulator: PTFE is used as an insulator for wiring and cable, especially in computers. 
• Lubricant: PTFE can reduce friction between surfaces and protect against corrosive substances. 
• Piping and tubing: PTFE coating prevents fluid leakage in facilities that handle corrosive fluids. 
• Fabric and textile: PTFE is water repellent and can be used to make garments and shoe fabrics. 
• Aerospace and aviation: PTFE provides electrical insulation for aircraft and spacecraft. 
• Breathable hydrophobic membranes: PTFE fine powders are used to create breathable hydrophobic membranes. 
• Aerospace/automotive hoses: PTFE fine powders are used to create aerospace/automotive hoses. 
• High-performance wires and cables: PTFE fine powders are used to create high-performance wires and cables. 

PTFE has unique properties, including:

• Nonreactivity
• Hydrophobicity
• Low coefficient of friction
• Good insulating properties
• High melting point
• Resistance to wear
