An explanation of the fluoropolymer PTFE, which has excellent gas barrier properties and high chemical resistance.
PTFE is a rare resin that excels in chemical resistance, heat resistance, and gas barrier properties.
PTFE (polytetrafluoroethylene) has a very stable molecular structure and excellent chemical resistance. It is also known for its particularly high gas barrier properties among fluoropolymers. This is because PTFE has very low permeability, making it difficult for gases and vapors to pass through. Therefore, it is suitable for use under harsh chemical conditions, such as in chemical plants and semiconductor manufacturing processes. Furthermore, PTFE has high heat resistance and can be used in a temperature range from -200°C to +260°C. This allows it to maintain its properties even under extreme temperature conditions. However, it is important to select the appropriate usage environment, as it may react with fluorine (gas) or alkali metals (sodium, potassium, lithium) under certain conditions. Fluoropolymer lining can form a lining with high gas barrier and chemical resistance properties on the substrate.

basic information
Fluoropolymer coatings are functional coatings that possess excellent properties such as: - Non-stick - Water and oil repellency - Heat and cold resistance - Low friction - Chemical resistance - Electrical properties PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy alkane) are types of fluoropolymers, both of which have outstanding chemical resistance. PTFE and PFA are resistant to chemicals and stable against acids, alkalis, organic solvents, and corrosive gases. They do not react with most substances and do not corrode or degrade. Therefore, they are widely used as chemical containers, piping, gaskets, and sealing materials. PFA has a lower melt viscosity compared to PTFE, making it relatively easy to mold and process. As a result, it expands the range of applications for coatings that require chemical resistance or thick film processing.
