Product Details

Expanded PTFE gasket Peng Nuo PN2400

The expanded polytetrafluoroethylene gasket is cut or stamped from 100% PTFE expanded polytetrafluoroethylene material. The expanded PTFE material (ePTFE) is a kind of expanded polytetrafluoroethylene. A tough and porous material that is highly fibrillated. This material not only retains the unique properties of Teflon itself - good chemical stability (not affected by general chemicals); very low coefficient of friction The wider operating temperature; does not age and is durable; now its multi-fiber structure makes it an unbelievable toughness as a sealing product, and more importantly, it fundamentally solves the common problems of other types of PTFE sealing materials. -- Creep and cold flow, greatly improved performance compared to pure PTFE gaskets and filled PTFE gaskets. In addition, easy to cut, easy to install, long service life and so on, it can be used in almost all sealing applications. Get the actual application. This is undoubtedly an amazing revolution.

Expanded PTFE gasket performance characteristics:

1, easy to cut, easy to install

It can be made easier by mechanical stamping or by hand cutting into a gasket of any shape.

2. Seal for rough surfaces

Expanded PTFE gaskets have a unique compliant forming capability that produces a good seal on rough or damaged flange faces without adding much pressure.

3.? Strong chemical resistance

Except for a few basic chemicals such as molten alkali metal, free fluorine, and tertiary nucleus, it does not react with any chemical substances. It can be applied in all sealing situations at the temperature (315 ° C), which will greatly reduce the variety of seals. And quantity.

4.? Good creep resistance and cold flow resistance

The unique high-density fiber structure gives it a strong creep resistance. Its mechanical properties are very stable due to the absence of any binders and additives.

Use industry: chemical, petrochemical, refining, chlor-alkali, acid, phosphate, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, non-ferrous smelting, steel, atomic energy and high-purity product production (such as ion-exchange membrane electrolysis), The transportation and operation of viscous materials, and the processing and production departments of food and beverages with strict requirements for hygiene.

PN2400 is suitable for various fluids under harsh working conditions, such as strong acid, strong alkali, gas, solvent, hydrocarbon, water, chlorine, aluminum fluoride, hydrogen oxide, etc., in petrochemical, caustic soda, chlor-alkali, Shipbuilding and other industries have achieved good results.

Use equipment: sealing parts of flange joints such as pipes, valves, pumps, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerators, etc., especially suitable for complex geometry, method The flange is not flat, the glass enamel and other special flanges are sealed.
