It has the property of repelling water and oil well, even when they are on the surface! It is also resistant to cold and can withstand low temperatures of -250°C.
"Fluororesin coating (Teflon coating)" is a surface treatment that imparts various properties of fluororesin to the surface of materials, achieving prevention of sticking and adhesion, reduction of friction, and protection of the materials. It exhibits excellent release properties even against strongly adhesive substances and is rarely affected by or corroded by chemicals such as acids and alkalis. The Teflon coating on household frying pans is an example of a fluororesin coating that utilizes the non-stick and heat-resistant characteristics of Teflon fluororesin to make it difficult for food to stick to the frying pan. 【Features and Effects】 ■ Non-stick: Excellent release properties even against strongly adhesive substances ■ Water and oil repellency: Effectively repels water and oil on the surface ■ Heat and cold resistance: Withstands high temperatures (up to 260°C) and low temperatures (down to -250°C) ■ Low friction: Has a low coefficient of friction, making it slippery ■ Chemical resistance: Rarely affected by or corroded by chemicals such as acids and alkalis ■ Electrical properties: High dielectric strength (resistance to dielectric breakdown), volume resistivity, and surface resistivity *For more details, please refer to the related links or feel free to contact us.
basic information
**Main Types** ■PTFE (Polytetrafluoroethylene) - Has a high continuous use temperature of 260°C and excellent heat resistance - Also excels in non-stick and low friction properties ■PFA (Perfluoroalkoxy alkane polymer) - An improved resin of PTFE, with the same continuous use temperature of 260°C - Can achieve a continuous coating with fewer pinholes ■FEP (Perfluoroethylene propylene copolymer) - An improved resin of PTFE, with lower heat resistance than PTFE - Can achieve a smooth coating with fewer pinholes through sintering ■ETFE (Ethylene-tetrafluoroethylene copolymer) - Excellent mechanical properties lead to superior wear resistance - Commonly used for anti-corrosion applications ■Modified Types - High-temperature modified type: Increases adhesion to the substrate without reducing the heat resistance of the fluororesin, improving wear resistance - Low-temperature modified type: Utilizes the low friction and non-stick properties of fluororesin, allowing for processing at low temperatures *For more details, please refer to the related links or feel free to contact us.*
