PTFE Bonded EPDM Gasket

PTFE Bonded EPDM Gasket

Cierne’s PTFE Bonded EPDM Gasket is made of high-grade EPDM or NBR as the main body, and the sealing part is compounded with a pure PTFE shell that has been specially activated. It has the advantage of adopting a special bonding process to make the PTFE plastic and synthetic rubber tightly bonded, and the overall composite is excellent.

Cierne’s PTFE Bonded EPDM Gasket reduces the cold flow of the gasket and increases the resistance of the gasket to blowout, so that the gasket has good rigidity and strength, compression, rebound, and compensation, and can be used in higher pressure and more demanding conditions.

Working pressure: PN≤25bar; Working temperature: ≤130℃

Advantages:

• Reusable gasket;
• Suitable for flanges made of PTFE, FRP, PVDF, polypropylene cast iron or ductile iron
•  The protruding sealing ring not only has the function of multiple labyrinth sealing, but also greatly reduces the sealing contact surface of the gasket and the flange, and can maintain a higher sealing specific pressure, thereby reducing 75% to achieve sealing. The torque load applied to the bolt, hence the name.
• The pure PTFE sealing surface provides a clean and pollution-free sealing surface, and also has very good chemical resistance.
• The unique compounding process firmly sticks PTFE on the rubber elastomer to prevent delamination and leakage.
• It is a good choice in the electronics industry and chemical plants.
