Teflon is a brand name for a synthetic chemical called polytetrafluoroethylene (PTFE). Teflon is used to coat a variety of products because it's waterproof, cuts down on friction, and creates a nonstick surface. Teflon has been used since the 1940s and it's found in everything from heat lamp bulbs to fabric protectors.
It is used in making waterproof fabric. It is used in making non-stick cookware. It is used in making an anti-friction device. It is used for coating medical appliances (surgical devices).
Teflon is heat and cold resistant. It can resist temperatures of up to 260C and can consistently operate of this level. Once this temperature is exceeded it will start to soften then at around 400C will start to give of fumes. If these fumes are inhaled it can cause flue type symptoms called polymer flue.
