TF6865 Modified PTFE Gasket G522 (Silicon Dioxide)

Modified PTFE Gasket G522 (Silicon Dioxide) Description

Modified PTFE Gasket G522 (Silicon Dioxide) provides a tight, leak-resistant seal with excellent chemical resistance and minimized creep relaxation. Reinforced with silicon dioxide, it performs reliably under harsh conditions involving strong acids (excluding hydrofluoric acid), solvents, hydrocarbons, water, steam, chlorine, and cryogenic media. It is especially suitable for acid service in polysilicon production and other demanding chemical processing environments.

Modified PTFE Gasket G522 (Silicon Dioxide) Applications

·       Strong acid systems (e.g., sulfuric acid, nitric acid, hydrochloric acid) — excluding hydrofluoric acid

·       Solvent pipelines and reaction vessels in chemical and pharmaceutical plants

·       Hydrocarbon processing in petrochemical units

·       Steam and hot water lines in chemical equipment

·       Chlorine service systems and chlorine dioxide generation units
