What are the differences between fluororesin, PTFE, and ETFE?

[Presentation of Materials] We will introduce the differences in characteristics between fluororesin "PTFE" and "ETFE" resins and coatings.

This explains the differences in characteristics between the fluoropolymer "PTFE" and "ETFE." ■Resin Name PTFE (Polytetrafluoroethylene) ■Characteristics It is the first resin discovered and developed among fluoropolymers. It has a continuous use temperature of 260°C, excellent heat resistance, low friction properties, and non-stick characteristics. Although it has a high melting viscosity, making injection molding difficult, it is used as a coating for frying pans and hot plates. ■Resin Name ETFE (Ethylene Tetrafluoroethylene Copolymer) ■Characteristics Unlike perfluorinated fluoropolymers, ETFE contains hydrogen atoms (H) in its molecular structure. Therefore, its chemical resistance and heat resistance are lower compared to PTFE and FEP, with a continuous use temperature of 150°C compared to PTFE's 260°C. On the other hand, ETFE has high mechanical strength and can be processed at low melting points, making it suitable for applications requiring corrosion lining and wear resistance. *For more details, please click on "PDF Download" or feel free to contact us.*

basic information

**Properties of Teflon Resin and Fluororesin** ■ Non-stickiness It has good release properties even against strongly adhesive substances, meaning it does not stick or is difficult to stick. ■ Water and Oil Repellency It repels water and oil well when they come into contact with the surface. Therefore, it is resistant to dirt and can be easily cleaned. ■ Heat and Cold Resistance Among resins, it has high heat resistance, enduring high temperatures (up to 260°C). It also withstands low temperatures down to -260°C. ■ Low Friction It has a slippery surface with a low friction coefficient. Additionally, it exhibits excellent lubricity. ■ Chemical Resistance It is rarely affected or corroded by chemical substances such as acids and alkalis. In the case of coatings, if the film is thin, it remains unaffected, but chemicals and solutions can penetrate the film and corrode the substrate, so increasing the thickness of the film helps prevent substrate corrosion. ■ Electrical Properties It has high insulation strength (dielectric breakdown strength), volume resistivity, and surface resistivity, making it excellent in electrical insulation.
