 Expanded PTFE Gasket Tape Data Sheet 

Expanded PTFE gasket tape, also referred to as expanded PTFE tape gasket or ePTFE tape, is a versatile sealing material engineered for reliable performance across a wide range of industrial applications. Manufactured from fully expanded polytetrafluoroethylene, the tape has a soft, conformable structure that adapts to surface irregularities, damaged flanges, or fragile materials, creating a uniform, leak-proof seal even under low bolt loads. Its inherent chemical inertness ensures compatibility with strong acids, alkalis, solvents, and high-purity process fluids, making it suitable for challenging chemical, pharmaceutical, food, and semiconductor environments.

The tape’s fibrillated microstructure provides excellent compressibility, low creep, and minimal cold flow, while its lightweight, non-contaminating composition allows easy handling and clean installation. Expanded PTFE tape can be cut, wrapped, or formed in place to accommodate complex flange geometries and large-diameter piping, eliminating the need for prefabricated gaskets. It maintains stable sealing performance across a wide temperature range and can withstand both intermittent and continuous operating conditions.

Widely used in valves, pumps, heat exchangers, reactors, and storage vessels, expanded PTFE tape combines flexibility, chemical resistance, and mechanical reliability, offering a cost-effective and long-lasting solution for industrial sealing challenges. Its ability to form custom seals quickly and efficiently makes it a preferred choice for engineers seeking dependable, maintenance-free performance in demanding environments.
