Expanded PTFE (Sealon) Tape: Superior Performance in High-Temperature Environments

South Eastern Gaskets’ expanded PTFE (Sealon) tape ensures superior sealing, withstanding high temperatures and chemicals for reliable performance.

In industries where extreme temperatures and harsh conditions are common, high-performance sealing solutions are essential to ensure operational efficiency and safety. Expanded PTFE (Sealon) tape is a durable and reliable sealing material designed to withstand extreme heat, pressure, and aggressive chemicals. Its versatility makes it a preferred choice across industries for ensuring leak-proof connections and optimal performance in demanding environments.

Unique Properties That Differentiate It from Standard PTFE Tape

Expanded PTFE (Sealon) tape offers superior performance over standard PTFE tape due to its soft, flexible, and highly adaptable structure. Its resistance to high temperatures beyond 260°C and chemical inertness make it ideal for sealing against aggressive substances like acids and solvents. With non-stick properties that prevent buildup, it reduces maintenance needs and extends equipment lifespan, ensuring reliability in demanding industrial environments.

Applications of Expanded PTFE (Sealon) Tape in Various Industries

Due to its outstanding thermal, chemical, and mechanical properties, expanded PTFE (Sealon) tape is widely utilised across multiple industries. Its adaptability allows it to provide effective sealing solutions in high-stress environments, ensuring optimal performance and safety.

•  Aerospace & Automotive – The aerospace and automotive sectors require materials capable of withstanding extreme temperatures and pressures. Expanded PTFE tape is used in engine gaskets, exhaust systems, and fuel line connections, providing reliable sealing that prevents leaks and enhances system efficiency. Its resistance to thermal expansion and chemical exposure ensures longevity in high-performance applications.

•  Petrochemical & Gas Processing – In the petrochemical and gas industries, sealing solutions must endure exposure to aggressive chemicals, high pressures, and fluctuating temperatures. Expanded PTFE tape is commonly employed in pipeline connections, flange gaskets, and valve seals, ensuring leak-free operation in hazardous environments. Its chemical inertness prevents degradation, reducing maintenance costs and enhancing operational safety.

•  Food & Pharmaceutical – Hygiene and contamination control are critical in food processing and pharmaceutical manufacturing. Expanded PTFE tape meets stringent industry standards, offering a non-toxic, non-contaminating sealing solution for equipment such as pumps, piping systems, and processing machinery. Its resistance to bacterial growth and ability to withstand high temperatures make it an ideal choice for maintaining sanitary conditions.

•  HVAC & Plumbing – The HVAC and plumbing industries rely on durable sealing materials to prevent leaks in steam lines, heating systems, and fluid transport networks. Expanded PTFE tape provides a secure and long-lasting seal for threaded connections, ensuring efficient operation and minimising the risk of system failures. Its flexibility allows it to conform to irregular surfaces, enhancing sealing performance in diverse applications.
