Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications due to its unique properties. It is more commonly known by the brand name Teflon, which is trademarked by Chemours Company. PTFE is a high molecular weight polymer and is known for its non-stick properties, high heat resistance, and low friction coefficient.
Properties of PTFE
- Non-stick: PTFE has a very low surface energy, which makes it extremely resistant to sticking to other materials.
- Heat resistance: PTFE can withstand high temperatures without degrading, making it suitable for use in various high-temperature applications.
- Chemical resistance: PTFE is highly resistant to chemical attack, including acids, bases, and organic solvents.
- Low friction: PTFE has a low coefficient of friction, which makes it an excellent choice for applications where reduced friction is desired.
Applications
PTFE is used in a wide range of applications, including:
- Cookware and bakeware coatings
- Industrial coatings for machinery and equipment
- Electrical insulation
- Gaskets and seals
- Medical implants and devices
- Non-stick coatings for fabrics and carpets
- Thread seal tape (commonly known as plumber's tape)
