WL Gore”s GR PTFE sheet gasketing has been upgraded with added dimensional stability. Featuring a newly patented microstructure, the sheet gasketing provides enhanced creep relaxation for better performance at elevated operating temperatures. Its improved sheet integrity helps prevent fractures that can occur due to improper gasket loading in exceptional circumstances, such as extreme flange deviation and misaligned flanges. The sheet gasketing can be used in most types of sealing applications. The material is impervious to virtually all chemicals, is suitable for use from -450 F to 600 F (-268 C to 315 C), and withstands pressures to 3,000 PSIG. The material also complies with FDA food requirements.
