Polytetrafluoroethylene (PTFE), commonly known as the "plastic king", is a high molecular polymer obtained by polymerization of tetrafluoroethylene as a monomer. Its chemical formula is (C2F4) n. It has excellent heat and cold resistance and can be used for a long time at -180~260 º C. This material has the characteristics of acid resistance, alkali resistance, and resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristic of high temperature resistance and extremely low friction coefficient, making it an ideal coating for easy cleaning of the inner layer of water pipes in addition to lubrication.
On October 27, 2017, the list of carcinogens released by the International Agency for Research on Cancer of the World Health Organization (WHO) was preliminarily sorted out for reference. Polytetrafluoroethylene (PTFE) was classified as one of the three carcinogens
