A PTFE Bonded EPDM Gasket is a high-performance sealing solution that combines the excellent sealing properties of PTFE(Polytetrafluoroethylene) with the flexibility and durability of EPDM (Ethylene Propylene Diene Monomer) rubber. The PTFE layer provides exceptional resistance to chemicals, high temperatures, and abrasion, while the EPDM core adds elasticity, resilience, and the ability to maintain a secure seal in dynamic environments. This type of gasket is ideal for applications in industries such as chemical processing, pharmaceuticals, food and beverage, and HVAC, where reliable and durable sealing is essential.

1. Chemical Resistance:PTFE is known for its outstanding chemical resistance. When bonded to EPDM, the gasket becomes highly resistant to a wide range of aggressive chemicals, acids, alkalis, and solvents. This makes it an excellent choice for applications in chemical processing, pharmaceuticals, and other industries where chemical exposure is a concern.
2. High Temperature Tolerance:PTFE can withstand high temperatures, up to 260°C (500°F), and the EPDM core maintains its flexibility and sealing performance at temperatures as low as -50°C (-58°F). This combination ensures the gasket performs reliably in both extreme heat and cold conditions.
3. Superior Sealing Performance:The PTFE layer provides a smooth, non-stick surface that enhances the sealing performance, preventing leaks in applications that involve high-pressure or challenging fluids. EPDM's excellent compression set resistance ensures the gasket maintains its shape over time, further improving sealing integrity.
4. Durability and Longevity:The combination of PTFE and EPDM results in a gasket that is not only durable but also long-lasting. PTFE provides resistance to wear, while EPDM adds resilience, ensuring the gasket remains effective in sealing over extended periods and reduces maintenance costs.
5. Versatility:PTFE bonded EPDM gaskets are highly versatile and can be customized to fit a wide variety of applications and industries. Whether you need custom sizes, thicknesses, or specific chemical resistance properties, PTFE bonded EPDM gaskets can be tailored to meet your needs.
6. Cost-Effective Solution:Compared to full PTFE gaskets, PTFE bonded EPDM gaskets offer a more cost-effective solution without compromising on performance. They deliver the chemical and temperature resistance of PTFE while benefiting from the affordability and resilience of EPDM.

• Chemical Processing:PTFE bonded EPDM gaskets are ideal for chemical processing applications, where resistance to aggressive chemicals and high temperatures is required. They are used in reactors, pumps, valves, and pipelines, ensuring safe and efficient operation of chemical plants.
• Food and Beverage:The non-reactive properties of PTFE, combined with the food-grade EPDM, make these gaskets suitable for the food and beverage industry. They provide a secure, sanitary seal in processing and packaging equipment, ensuring compliance with FDA regulations.
• Pharmaceuticals:In the pharmaceutical industry, cleanliness and chemical resistance are paramount. PTFE bonded EPDM gaskets are used in systems involving sterile processing, where high temperatures, pressures, and exposure to chemicals are common.
• HVAC Systems:PTFE bonded EPDM gaskets are widely used in HVAC systems for sealing ducts, valves, and other components. They maintain a tight seal under pressure and temperature variations, improving the efficiency of heating and cooling systems.
• Water Treatment:These gaskets are also effective in water treatment plants, where they are used to seal pipes and valves. Their resistance to water and a variety of chemicals ensures long-lasting and leak-proof performance.
• Automotive:PTFE bonded EPDM gaskets are used in automotive applications, especially for sealing engine components, fuel systems, and exhaust systems. They provide a durable seal that withstands the pressures and temperatures common in engine environments.
