The product has extremely high insulation, chemical stability, and good sealing performance, and is widely used in various industrial fields such as machinery, chemical industry, metallurgy, power, shipbuilding, aerospace, medicine, electronics, etc.
Polytetrafluoroethylene is a polymer of tetrafluoroethylene, abbreviated as PTFE in English.
The basic structure of polytetrafluoroethylene is - CF2- CF2- CF2- CF2- CF2- CF2- CF2- CF2- CF2-
Polytetrafluoroethylene is widely used in various applications that require resistance to acids, bases, and organic solvents. It itself is not toxic to humans, but one of the raw materials used in the production process, perfluorooctanoic acid ammonium (PFOA), is believed to have carcinogenic effects.

Due to its non-toxic, odorless, excellent sealing, insulation, and corrosion resistance, it is widely used in fields such as water treatment, natural gas, chemical engineering, plastics, and electronic engineering. Polytetrafluoroethylene has a relatively large molecular weight, ranging from tens of thousands to over 10 million, and generally in the millions (with a degree of polymerization on the order of 104, while polyethylene is only 103). The general crystallinity is 90-95%, and the melting temperature is 327-342 ℃. The CF2 units in polytetrafluoroethylene molecules are arranged in a zigzag shape. Due to the slightly larger radius of fluorine atoms compared to hydrogen, adjacent CF2 units cannot be oriented in a trans cross manner, but instead form a helical twisted chain, with fluorine atoms covering almost the entire surface of the polymer chain. This molecular structure explains the various properties of polytetrafluoroethylene. When the temperature is below 19 ℃, a 13/6 helix is formed; At 19 ℃, a phase transition occurs, causing the molecules to slightly unravel and form a 15/7 helix.
