Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer made from tetrafluoroethylene, known for its chemical inertness. It has a wide range of applications due to its resistance to chemical reactions. The most well-known brand name for PTFE-based products is Teflon, developed by Chemours, a company that originated as a spin-off from DuPont, which first discovered PTFE in 1938. It is a polymer made from tetrafluoroethylene and was discovered by Roy J. Plunkett in 1938. Its chemical name is polytetrafluoroethene (C₂F₄)n. It is a nonstick material commonly used for coating cooking utensils and industrial equipment to prevent sticking.
Teflon coating
Properties:
- Teflon is a white solid at room temperature with a density of 2.2 g/cm³.
- It has a high melting point of 600 K and excellent resistance to heat and cold.
- It is chemically resistant, affected only by alkali metals, and does not react with most substances.
- Teflon’s non-stick surface prevents water, oil, and other materials from adhering, making it ideal for cookware.
- It is highly durable, unaffected by weather or chemicals, and easy to clean.
- Its low water absorption and anti-adhesion properties make it suitable for both household and industrial use.
