In chemistry, Polytetrafluoroethylene (often shortened to PTFE) is a polymer of tetrafluoroethylene. It is a fluoropolymer, because the polymerization is based on strong covalent bonds of fluorine and carbon. Polytetrafluoroethylene is not very reactive. It also repels oil and water. E. I. du Pont de Nemours and Company developed it in 1938.
Problems[change | change source]
The precursors for many chemical weapons are highly corrosive, so their containers are often treated with Polytetrafluoroethylene. For this reason, the export of Polytetrafluoroethylene from the European Union may need a special permit.
