Teflon® Characteristics
Teflon® is considered to be the most slippery material that exists. It withstands extreme temperatures, is an excellent insulator, and is resistant to nearly all industrial chemicals and solvents. Because it has a low coefficient of friction, it is a superb choice for applications in which materials will slide against one another and is often used for products that need an anti-stick surface – including cooking pots and pans.
Teflon® – a polytetrafluoroethylene (PTFE) has outstanding dielectric properties that remain stable with frequency and temperature. It resists ignition and does not promote the spread of flames. Teflon® has a uniquely high bulk density. Characteristics include:
- Excellent thermal and electrical insulation properties
- Low coefficient of friction
FDA approved for food contact- Chemical resistant
- UL94-VO flame rating
Applications for Teflon®
- Bearings
- Bushings
- Gears
- Slide plates
- Piston rings
- Seals
