Answer:
Teflon is a brand name of a chemical coating, polytetrafluoroethylene (thankfully shortened and called PTFE). It was first made in the 1930s to create a non-reactive, nonstick surface. It's known for its use in cookware, although it can also be used to coat other materials like wires or fabrics to make them waterproof.
