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.
