PTFE stands for polytetrafluoroethylene and is a synthetic fluoropolymer of tetrafluoroethylene. It is commonly known by the brand name Teflon, which is produced by Chemours Company. PTFE is a highly versatile and heat-resistant material that is used in a wide range of applications, including non-stick coatings for cookware and bakeware, as well as in industries such as aerospace, automotive, and medical. PTFE has a low coefficient of friction, which means it is resistant to sticking and provides a smooth, non-stick surface. However, PTFE can release toxic fumes when heated to high temperatures, which can cause instant death to nearby birds while inciting flu-like symptoms in people. PTFE overheats and begins vaping toxic fumes at between 536°F and 660°F, depending on the brand's exact composition.
