Definition

Noun: A synthetic polymer resin consisting of carbon and fluorine atoms, known for its extremely low coefficient of friction, high heat resistance, and chemical inertness. It is a fluorocarbon solid.

Usage

This is a technical, scientific term. It is used as a mass noun (uncountable) to refer to the material itself. It is most commonly used in industrial, engineering, and chemical contexts.

Examples

• Non-stick cookware is often coated with polytetrafluoroethylene.
• The chemical inertness of polytetrafluoroethylene makes it suitable for seals and gaskets in aggressive environments.
• A key property of polytetrafluoroethylene is its resistance to almost all chemicals.

Advanced Usage

• As a proprietary eponym: While "polytetrafluoroethylene" is the generic chemical name, it is famously known and marketed under the brand name Teflon®. In informal or commercial contexts, people often use the brand name instead of the full chemical term.
  • Informal: "The pan has a Teflon coating."
  • Formal/Technical: "The component is made from polytetrafluoroethylene."
