Expanded PTFE gasket is made of 100% PTFE expanded PTFE material cut or stamped. Expanded PTFE material (EPTFE) is expanded into a strong and porous unique material. Expanded PTFE gasket is white, elastic and flexible, can be arbitrarily bent (over 360 degrees). Expanded polytetrafluoroethylene has good chemical resistance, wear resistance and strong resistance to high temperature, low temperature ability, very suitable for industrial liquid sealing.

Size:（DN10~DN2000）、JIS(10A~2000A)、ASMB-16.5

Advantages

1. Easy to cut, can be cut into any shape of gasket by mechanical stamping or hand. It is convenient for people to install and use, so that your work becomes more convenient.

2. Because the expanded PTFE gasket has a unique adaptability to forming ability. Therefore, when we install and use, we can produce good sealing effect on rough or damaged flange surface without increasing much pressure.

3. It has strong chemical corrosion resistance. In addition to melt alkali metal, free fluorine, tertiary nuclear and other very few chemical substances do not react with any chemical substances. Therefore, the expanded ptfe gasket can be used in all sealing situations within the temperature (315℃) allowed range. This will greatly reduce the variety and quantity of seals.

4. Due to the unique high-density fiber structure of expanded PTFE material, it has strong creep resistance; Because it does not contain any adhesives and additives, its mechanical properties are very stable.

Application

1. Due to the expansion of ptfe gasket can be used for a variety of different hardness interface sealing, such as :(1) rigid metal interface (generally used for 3㎜); (2) FRP interface (generally used for 3㎜); (3) plastic lining interface (used below or equal to DN300 caliber); (4) Enamel, steel lining glass interface for use.

2. Due to the good leakage resistance of expanded tetrafluoride gasket, the gas leakage rate is less than 1×10-4. Therefore, expandable tetrafluoride gasket can also be used for corrosive gas sealing, such as chlorine, vinyl chloride gas, etc., to help many large caustic soda plant, chlorine alkali plant to solve the leakage problem of chlorine gas.
