Expanded PTFE Gaskets are high-performance sealing materials made from expanded polytetrafluoroethylene (ePTFE), offering exceptional flexibility and sealing capabilities. Their unique microporous structure enables superior sealing under low stress while maintaining high chemical and temperature resistance. Suitable for extreme temperature environments, ePTFE gaskets operate from -240°C to +260°C and resist corrosion from most acids, alkalis, and solvents. Additionally, their low density (0.4-0.8 g/cm³) and lightweight design make them ideal for various industrial applications.
Expanded PTFE Gaskets feature excellent compressibility and recovery rates, with compression rates of 20-40% and recovery rates exceeding 50%, ensuring stable sealing performance even after repeated compression. Their thickness can be customized, typically ranging from 1mm to 3mm, making them suitable for sealing flanges and joints. Expanded PTFE Gaskets are widely used in chemical, pharmaceutical, food processing, and semiconductor industries, particularly in applications requiring high cleanliness and corrosion resistance. Their white color and smooth surface also make them a preferred choice for food-grade applications.
