Resin gasket

PTFEpolytetrafluoroethylenedrinking water

Polytetrafluoroethylene gasket (PTFE gasket, commonly known as "Teflon gasket") is a sealing gasket pressed or turned from pure polytetrafluoroethylene resin or its modified materials. It has excellent chemical corrosion resistance, high and low temperature resistance, low friction and excellent insulation properties. It is one of the important materials in the sealing field of chemical, pharmaceutical, food and other industries. DESCRIPTION 1. Main features of polytetrafluoroethylene gaskets: Excellent corrosion resistance PTFE can withstand almost all strong acids, strong alkalis, oxidants, organic solvents and corrosive gases. It is the only choice for sealing extreme chemical media and is suitable for all environments with a pH range of 0~14. Excellent high and low temperature resistance It can work stably for a long time in the temperature range of -200℃ to +260℃ without brittle cracking or softening, and is suitable for equipment sealing under extremely cold or high temperature conditions. Extremely low friction coefficient and self-lubrication The surface is smooth, the friction is small, it is not easy to adhere to impurities or scale, it is easy to disassemble and reuse, and it is especially suitable for pure or pollution-free occasions. Good electrical insulation performance The dielectric constant is stable and the volume resistivity is extremely high. It can be used in the field of electrical and electronic sealing. Non-toxic, tasteless, physiologically inert It complies with food and medical safety standards such as FDA and USP, and can be used in drinking water, food, pharmaceuticals, medical devices and other industries.
