TF6872 Modified PTFE Sheet S522 (Silicon Dioxide)

Modified PTFE Sheet S522 (Silicon Dioxide) Description

Modified PTFE Sheet S522 (Silicon Dioxide) is a high-performance gasket sheet material made from chemically resistant PTFE filled with silicon dioxide. This formulation significantly enhances the sheet’s mechanical strength, reduces creep and cold flow, and ensures stable sealing performance under high chemical and thermal stress. S522 is particularly suitable for applications involving strong acids (except hydrofluoric acid), solvents, hydrocarbons, steam, and low-temperature media, making it ideal for demanding sealing environments in the chemical, pharmaceutical, and petrochemical industries.

Modified PTFE Sheet S522 (Silicon Dioxide) Applications

·       Chemical processing plants – sealing pipelines, pumps, and vessels handling strong acids, solvents, and corrosive fluids

·       Pharmaceutical industry – used in clean and chemically aggressive environments requiring high sealing reliability

·       Petrochemical and refinery systems – ideal for hydrocarbon and chlorine-containing media under pressure and temperature variations

·       Steam and utility lines – compatible with high-temperature steam and water systems

·       Flange sealing – for glass-lined equipment, uneven flanges, and corroded or rough sealing surfaces

·       Low-temperature service – suitable for sealing refrigerants and cryogenic fluids in industrial gas systems
