Polytetrafluoroethene (Polytetrafluoroethene), the English abbreviation is PTFE, commonly known as "Plastic King", brand name Teflon®, in China, due to the pronunciation, the trademark "Teflon" is also called Teflon, Teflon , Teflon, Teflon, Teflon, etc., are all transliterations of Teflon.
Many people will ask what is the difference between Teflon and Teflon? Actually, there is no difference! Because Teflon is Teflon, they are different names of the same product. Teflon is also called Teflon, Teflon, Teflon, and Teflon. They are all homophonic sounds of teflon and are a kind of coating produced by DuPont.

Products of this material are generally collectively referred to as "non-stick coating"; it is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used for lubrication, and it has also become an ideal coating for non-stick pots and water pipes.
The performance characteristics of PTFE mainly include high and low temperature resistance, chemical corrosion resistance and weather resistance, small friction coefficient, self-lubricating and non-sticky, etc., so PTFE is anticorrosive materials, oil-free lubricating materials, electronic Advanced medium materials, medical materials and anti-stick materials for equipment.
Although PTFE material has excellent properties that other materials cannot replace, it also has shortcomings 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 many fields such as petrochemical industry, electronics, and medical treatment.
Polytetrafluoroethylene is a polymer compound formed by polymerization of tetrafluoroethylene. It has excellent chemical stability and corrosion resistance (it is one of the best corrosion resistance materials in the world today, except for molten sodium and liquid fluorine. , Can withstand all other chemicals, does not change when boiled in aqua regia, widely used in all kinds of anti-acid, alkali and organic solvents), sealing, high lubrication and non-stick, electrical insulation and good anti-aging endurance, resistance Excellent temperature (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, perfluorooctanoate (PFOA), is thought to have carcinogenic effects.
So is Teflon poisonous?
As the source manufacturer, we (Miss Teflon tube) tell everyone that Teflon is a special plastic that will produce carcinogenic toxins at high temperatures. Animal experiments have shown that long-term use of container products containing Teflon can cause plague. Now, some foreign countries have explicitly banned the use of products containing Teflon, especially pots and other products. Non-stick pans use Teflon, the scientific name of polytetrafluoroethylene (the same is the raw material tape with the faucet), and the outstanding chemical The characteristic is that it is difficult to corrode. Even aqua regia (corrosive to platinum) can't be used. Everything is perfect, except for one: this plastic will start to decompose when heated to 260 degrees Celsius, and it will release harmful substances to the human body when it reaches 350 degrees Celsius. However, the temperature of the pots used at home (especially rice cookers) is far less than 260 degrees, even if it is hot oil, it will not exceed 260 degrees, so don’t worry.
Shenzhen DanKai Technology Co., Ltd. (ShenZhen DanKai Technology Co.,ltd.), whose predecessor was Dongguan Dandi Insulation Material Co., Ltd.
