What is PTFE Teflon?

Teflon PTFE (Polytetrafluoroethylene) sounds like Teflon, Teflon, Teflon, etc. (all are transliterations of Teflon).Also known as polytetrafluoroethylene, PTFE In response to the needs of the use environment, Teflon has developed several basic types of PVDF, PTFE, FEP, PFA, ETFE, and NEW-PTFE. PTFE is a widely used fluorocarbon polymer.

The types of Teflon (Teflon) can be divided into several basic types: PTFE, FEP, PFA, and ETFE.Teflon (Teflon) PTFE: also known as polytetrafluoroethylene, is a non-stick coating that can be used continuously at 260°C, with a maximum service temperature of 290-300°C, extremely low coefficient of friction, good wear resistance and extremely Good chemical stability.Teflon (Teflon) FEP: also known as fluorinated ethylene propylene copolymer, which melts and flows to form a non-porous film for non-stick coatings during baking. Teflon has excellent chemical stability and excellent non-stick properties. Features, Teflon PTFE commonly known as Teflon, corrosion resistance, high and low temperature resistance, surface non-stick, non-combustible, but the hardness is not high.Teflon PTFE Uses: Semiconductor components, mechanical parts.



What is the difference between Teflon and PTFE?

Teflon (Teflon) PTFE: also known as polytetrafluoroethylene, is a non-stick coating that can be used continuously at 260°C, with a maximum service temperature of 290-300°C, extremely low coefficient of friction, good wear resistance and extremely Good chemical stability.
The basic types can be divided into PTFE, FEP, PFA, ETFE

PTFEIt 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 solventsPTFEPTFEThe non-stick coating can be used continuously at a high temperature of 260°C, and the instantaneous use temperature is as high as 290-300°C.PTFEhas an extremely low coefficient of friction,PTFEAbrasion resistance and chemical stability.

FEP: Fluorinated ethylene propylene is a copolymer of hexafluoropropylene and tetrafluoroethylene.It differs from PTFE resins in that it can be melt processed using conventional injection molding and screw extrusion techniques.Fluorinated ethylene propylene was invented by DuPont and sold under the trade name of Teflon FEP, a copolymer of hexafluoropropylene, a non-stick coating that melts and flows when baked to form a non-porous film with excellent chemical stability and non-stick properties , the maximum operating temperature is 200°C.

PFA: perfluoroalkyl vinyl ether copolymer resin, non-stick coating melts and flows to form a non-porous film during baking (same as FEP).The continuous use temperature is 260°C, stronger rigidity and toughness, especially suitable for anti-sticking and chemical resistance applications under high temperature conditions.(hydrofluoric acid, etchant)

TFM: A new type of PTFE (PTFE+PFA), which has a stronger polymer structure without reducing the characteristics of PTFE, and is suitable for chemicals and gases
Less permeable.Welding construction can be welded, the machined surface is smoother, and injection molding can be carried out in special cases.

ECTFE: Copolymer of ethylene and tetrafluoroethylene, the toughest fluoropolymer.Good at forming a highly durable coating with excellent chemical resistance,
It can work continuously at 150 ℃.
PVDF: Polyvinylidene fluoride is an opaque, semi-crystalline thermoplastic fluoropolymer.PVDF offers excellent chemical resistance without the low mechanical values ​​and/or processing difficulties typically encountered with other fluoropolymer materials.The melting point of PVDF material is 171 degrees Celsius



What are the characteristics of PTFE Teflon (Teflon)?

Teflon (Teflon) 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, and its friction coefficient is extremely low, so it can be used for lubrication, and it has also become an ideal coating for non-stick pans and the inner layer of water pipes.The mechanical strength of PTFE is slightly lower than that of other plastics, but its mechanical properties can be effectively strengthened by adding composite materials such as glass fiber, carbon fiber or copper fiber. PTFE, FEP, PFA, and ETFE play the best functions in various environments.PTFE has excellent temperature resistance, chemical resistance, and drug resistance. Its melting point is 327°C, and it can be used at extremely low temperatures down to minus 170°C. It is an excellent heat-resistant material.It will not react to concentrated sulfuric acid and boiled aqua regia. In various extremely harsh environments, PTFE, FEP, PFA, and ETFE will be excellent application materials
