PTFE rubber composite gasket: compared with other PTFE rubber composite gasket, its * big advantage is the use of special bonding process to make the PTFE plastic and synthetic rubber close bonding, excellent overall compound.The product has excellent corrosion resistance, non - toxic, anti - viscosity, and has good elasticity and sealing performance. 

PTFE rubber composite gasket is made of advanced EPDM EPDM or NBR butadiene nitrile rubber as the main body, and the effective sealing part is compounded with 100% pure PTFE shell after special activation treatment. 

The product reduces the cold flow of gasket, and increases the anti-blowing property of gasket, so that gasket has good rigidity strength and compression, rebound, compensation, can meet the higher pressure and more demanding conditions. 

Using pressure: PN 25 or less bar, the use of temperature: 130 ℃ or less

Ii. Main advantages:

Is the only reusable gasket; 

This perfect gasket is suitable for flanges made of ptfe, FRP, PVDF, polypropylene cast iron or ductile iron

The raised seal ring not only has the function of multiple labyrinth seals, but also greatly reduces the sealing contact surface between gasket and flange, which can maintain a high seal specific pressure, thus reducing the torque load imposed on the bolt to achieve the seal by 75%, hence the name.
