The main material of PTFE is Teflon , Teflon is a pure white polymer plastic material. However, polytetrafluoroethylene PTFE materials can be added to different colors to form different colors. The full name of polytetrafluoroethylene in English is Polytetrafluoroetylene, called Teflon, PTFE, F4 and so on. Teflon PTFE (Polytetrafluoroethene), commonly known as "non stick coating" or "easy to clean wok materials"; is a fluorine substituted all hydrogen atoms in polyethylene synthetic polymer materials. This material has the characteristics of anti - acid, alkali, anti - organic solvent and almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, the friction coefficient is very low, so it can be used as lubricant remaining, also became the ideal coating and the inner pipe easy to clean wok. Synthetic material is Teflon PTFE plastic powder, in the form of sintering in the other surface of the material, such as pan, oil bearings, bushings, bearing. It can be sintered on the surface of a metal material. No transparent teflon! Teflon coated on the metal top can. But with precious metals above is too bad, because the price is very expensive.
