Polytetrafluoroethylene (Polytetrafluoroethene), English abbreviation for PTFE, commonly known as "plastic king", brand name Teflon®In China, because of the pronunciation, "Teflon" is also called Teflon, Teflon, Teflon, Teflon, Teflon, Teflon, etc., all of which are transliterations of Teflon.
Many people will ask what is the difference between Teflon and Teflon? In fact, there is no difference! Because Teflon is Teflon, they are different names for the same product. Teflon is also called Teflon, Teflon, Teflon, Teflon, they are teflon homophonic, is the United States DuPont production of a coating.

Products of this material are generally referred to as "non-stick coating"; it is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of acid and alkali resistance, resistance to various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its coefficient of friction is very low, so it can be used for lubrication, and it has become an ideal coating for non-stick pot and water pipe inner layer.
The performance characteristics of PTFE are mainly high and low temperature resistance, chemical corrosion resistance and weather resistance, low friction coefficient, self-lubrication and non-stick and many other excellent properties, so PTFE is anti-corrosion materials, oil-free lubrication materials, advanced media materials for electronic equipment, medical materials and anti-sticking materials.
Although PTFE material has excellent properties that cannot be replaced by other materials, it also has disadvantages such as high melt viscosity, high expansion coefficient, and cold flow. With the continuous development of material application technology, researchers are gradually overcoming these shortcomings of PTFE and applying it in petrochemical, electronics, medical and many other fields.
Polytetrafluoroethylene is a polymer compound formed by polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance (it is one of the best materials for corrosion resistance in the world today. In addition to molten metal sodium and liquid fluorine, it can withstand all other chemicals and cannot change when boiled in king water, widely used in all kinds of need to resist acid and alkali and organic solvents), sealing, high lubrication non-stick, electrical insulation and good anti-aging endurance, excellent temperature resistance (can work at a temperature of 250 ℃ to -180 ℃ for a long time). Polytetrafluoroethylene itself is not toxic to humans, but one of the raw materials used in the production process, ammonium perfluorooctanoate (PFOA), is considered to be carcinogenic.
Is Teflon poisonous?
As the source manufacturer, we (the little sister of Teflon tube) told everyone that Teflon is a special plastic, which will produce carcinogenic toxins at high temperatures. Animal experiments show that long-term use of container products containing Teflon can cause plague. Now some foreign countries have banned the use of products containing Teflon, especially pots and other products. Teflon is used for non-stick pots, and the scientific name is polytetrafluoroethylene (the raw material belt including faucet is also), the outstanding chemical characteristic is that it is difficult to corrode. Even aqua aqua (which can corrode platinum) can't take it. Everything is perfect except one: this plastic will start to decompose when heated to 260 degrees Celsius, and will release substances harmful to human body when heated to 350 degrees Celsius. However, the temperature of the general household pots (especially electric rice cookers) is far less than 260 degrees, and even hot oil will not exceed 260 degrees. Therefore, don't worry about it.
