The biggest advantage of rubber PTFE composite gasket compared to other PTFE coated gaskets is the use of a special melt bonding process to tightly fuse PTFE plastic with synthetic rubber, resulting in excellent overall composite performance. This product has excellent corrosion resistance, non toxicity, anti adhesion, as well as good elasticity and sealing performance.
Operating pressure: PN ≤ 25bar, operating temperature: ≤ 150oC
PTFE rubber composite gasket is made of high-grade EPDM ternary ethylene propylene rubber or NBR nitrile rubber as the main body, and is compounded with a 100% pure PTFE shell that has been specially activated in its effective sealing area.
The product reduces the cold flow of the gasket and increases its resistance to blow out, making the gasket have good rigidity, strength, compression, rebound, and compensation, which can meet high pressure and harsh working conditions.
2、 Main advantages
1. It is the only reusable gasket;
2. This perfect gasket is suitable for polytetrafluoroethylene, fiberglass PVDF、 Flanges made of polypropylene cast iron or ductile iron
3. The protruding sealing ring not only has multiple labyrinth sealing functions, but also greatly reduces the sealing contact surface between the gasket and the flange, which can maintain a high sealing pressure and reduce 75% of the torque load applied to the bolt 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 unique composite process firmly adheres PTFE to the rubber elastomer, preventing delamination and leakage.
6. It is the best choice in the electronics industry, chemical plants, and pharmaceutical factories.
