What types of fluororesins are suitable for applications such as non-adhesiveness, slip properties, and corrosion resistance? It is necessary to consider the characteristics and properties of the resin, as well as the selection of processing methods.
**Representative Types** ■ PTFE (Polytetrafluoroethylene) It has the highest continuous use temperature of 260°C and excels in non-stick and low friction properties. ■ PFA (Perfluoroalkoxyalkane Polymer) It has a low melt viscosity and can achieve a continuous coating with fewer pinholes than PTFE. It is the best-performing fluororesin for high-temperature corrosion resistance. ■ FEP (Perfluoroethylene Propylene Copolymer) An improved resin of PTFE, it has a lower continuous use temperature than PTFE but can achieve a smooth coating with fewer pinholes through sintering. ■ ETFE (Ethylene-Tetrafluoroethylene Copolymer) Due to its excellent mechanical properties, it is highly resistant to wear and is often used for anti-corrosion applications. ■ Modified Types ◎ High-temperature modified type ◎ Low-temperature modified type **Representative Processing Methods** ○ The enamel of fluororesin is applied using a painting machine or manually. ○ Fluororesin powder is applied using electrostatic or special painting machines. Coating processing is easily adaptable to complex shapes and is used in numerous industries. *For more details, please download the PDF and take a look.*
