Teflon Film Manufacturers Analysis of Teflon Material Description: Teflon (Teflon), English name Teflon, is usually called Teflon, Teflon, Teflon, etc. because of pronunciation. It can also be called polytetrafluoroethylene. Kill

Teflon coating is the 1 high-performance coating, combining heat resistance, chemical inertness and excellent insulation stability and low friction, with other coatings can not compete with the comprehensive advantages, its application flexibility makes it can be used in almost all shapes and sizes of products.

The type of Teflon (Teflon) can be divided into several basic types of PTFE, FEP, PFA, and ETFE. Kill

Teflon (Teflon) PTFE: also known as polytetrafluoroethylene, non-sticky coating can be used continuously at 260 ℃, with a maximum use temperature of 290-300 ℃, low friction, good wear resistance and excellent chemical stability. Kill

Teflon (Teflon) FEP: also known as fluorinated ethylene propylene copolymer, is a non-stick coating that melts and flows during baking to form a non-porous film. It has excellent chemical and good non-stick characteristics. The maximum use temperature is 200 ℃. Kill

Teflon (Teflon) PFA: also known as perfluoroalkylate, is a non-stick coating that melts and flows during baking to form a non-porous film like FEP. The advantage of PFA is that it has a higher continuous use temperature of 260 ℃, stronger rigidity and toughness, and is especially suitable for use in the field of anti-sticking and chemical resistance under high temperature conditions. Kill

Teflon (Teflon) ETFE: is a tough 1 copolymer of ethylene and tetrafluoroethylene. This fluoropolymer can form a highly durable coating, excellent chemical resistance, and can work continuously at 150 ℃. Kan Kan

The nature of Teflon (Teflon) in fluoroplastics, Teflon consumption and wide use, it is an important variety of fluoroplastics. Kill

The chemical structure of Teflon is to replace all the hydrogen atoms in polyethylene with fluorine atoms. Its molecular formula is: PTFE in the molecule: F in the atom, cover the bond of C- C and C- F in the bond energy is high and especially stable, and it is not attacked by any chemicals except alkali metals and elemental fluorine. In PTFE, there is atomic symmetry in the molecule. In C- F, two elements are covalently bonded. There are no free electrons in the molecule. The whole molecule is neutral. It makes PTFE have excellent dielectric properties because it has no gram bonds in its molecular structure, so its crystallinity is very high. Because PTFE has an inert fluorine-containing outer shell, it has outstanding non-stick properties and a low coefficient of friction. Kill

Teflon has excellent high and low temperature performance and chemical stability, is very good electrical insulation, non-adhesion, weather resistance, non-burning and good lubricity. PTFE was developed for national defense and cutting-edge technology needs, and then gradually extended to civilian use. Its use involves aerospace, petrochemical, machinery, electronics, construction, textile and other industrial sectors. It is an indispensable material to solve many key technologies of modern science and technology, military and civilian use, and to improve the level of production technology. Teflon's characteristics are unmatched by other plastics, and it is known as the "plastic king.
