Tetrafluororubber composite diaphragm

1、 Product Description:

1) Tetrafluororubber composite gasket: Compared with other PTFE encapsulated gaskets, the advantage of PTFE composite gasket is the use of special bonding technology to tightly bond PTFE plastic with synthetic rubber, resulting in better overall composite performance. This product has excellent corrosion resistance, anti adhesion, as well as good elasticity and sealing performance.

2) The PTFE composite gasket is made of EPDM EPDM or NBR nitrile rubber as the main body, and is compounded with a specially activated pure PTFE shell at its effective sealing area.

3) The product reduces the cold flow of the gasket and increases its resistance to blowing out, making the gasket have good rigidity, strength, compression, rebound, and compensation, which can meet high pressure and harsh working conditions.

4) Operating pressure: PN ≤ 25bar, operating temperature: ≤ 130 ℃

2、 Main advantages:

1) It is the only reusable gasket;

2) This gasket is suitable for flanges made of polytetrafluoroethylene, fiberglass, PVDF, polypropylene cast iron, or ductile iron

3) The raised sealing ring not only has multiple labyrinth sealing functions, but also greatly reduces the sealing contact surface between the gasket and flange, maintaining a high sealing pressure ratio, thereby reducing the torque load applied to the bolt by 75% to achieve sealing, hence the name.

4) 100% pure PTFE sealing surface provides a clean and pollution-free sealing surface, while also having excellent chemical resistance.

5) The composite process firmly adheres PTFE to the rubber elastomer, preventing delamination and leakage.

6) It is a better choice in the electronics industry, chemical factories, and pharmaceutical factories.
