The past and present life of polytetrafluoroethylene

Polytetrafluoroethylene (PTFE) was discovered by chemist Dr Roy J. Plunkett in DuPont’s Jackson Laboratory in New Jersey in 1938. When he tried to make a new CFC refrigerant, polytetrafluoroethylene polymerized in a high-pressure storage vessel (the iron on the inner wall of the vessel became the catalyst for the polymerization reaction). DuPont company obtained its patent in 1941 and registered its trademark under the name of “TEFLON” in 1944. Later, DuPont started its business in Teflon & reg; In addition to PTFE resin, we have developed a series of products, including Teflon; AF (amorphous fluoropolymer), Teflon; FEP (fluorinated ethylene propylene resin), Teflon; FFR (fluoropolymer foam resin), Teflon; NXT (fluoropolymer resin), Teflon; PFA (perfluoroalkoxy resin) and so on.

Teflon conveyor belt

The products of this material are generally referred to as “non stick coating”; It is a kind of synthetic polymer material which uses fluorine to replace all hydrogen atoms in polyethylene. This material has the characteristics of acid resistance, alkali resistance and various organic solvents, and it is almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature resistance, and its friction coefficient is very low, so it can be used as lubrication, and also become an ideal coating without the oil pan and the inner layer of water pipe.

Teflon can be used in conveyor belt: Teflon conveyor belt, Teflon conveyor belt, cold skin conveyor belt, pipeline conveyor belt, Teflon cloth, PTFE cloth belt, carpet belt, door mat cloth, food conveyor belt, etc. Of course, we can also use it on the tape: Teflon adhesive tape, Teflon glass fiber adhesive tape, Teflon high temperature resistant tape, self adhesive tape, self adhesive welding cloth, etc.
