Description:ZD-GS1620 Semirigid Expanded PTFE Sheet is a structural modified PTFE high elastic soft gasket made by advanced production technology. It provides high quality raw fiber to solve the problem of creep relaxation and cold flow in common PTFE sheet. ZD-GS1620 is more than advanced in many aspects. The expanded teflon plate of the mouth and all kinds of imported modified PTFE filled plates have proved that ZD-GS1620 is a structural modification material that can completely replace the imported PTFE, and its price is reasonable and has a high cost performance. It has many excellent properties, such as creep resistance, cold resistance, super low temperature, no pollution, easy installation and replacement.
The performance characteristics of the hard expanded tetrafluoroplate:
1, 100% pure PTFE, good chemical resistance.
2, the molecular structure is multi-directional. Besides the advantages of ordinary PTFE, it has the characteristics of cold resistance and creep resistance.
3. It can be used to seal a variety of different hardness interfaces.
(1) rigid metal interface (usually 3 mm)
(2) glass steel interface (general use 3 mm)
(3) plastic lining interface (below or below DN300 diameter).
(4) the use of enamel, glass lined steel interface.
4, ZD-GS1620 has good leakage resistance and the gas leakage rate is less than 1 * 10-4. It can be used for corrosive gas seal, such as chlorine gas, chloroethylene gas and so on. It helps many large caustic soda plants and chlor alkali plants to solve the leakage of chlorine gas and so on. It is the only domestic high performance material with two performance of chlor gas in China. It is in the chlor alkali industry. Good word of mouth.
5, ZD-GS1620 rigid expansion PTFE plate for turning plate, plate surface smoothness.
6, the following 5 kinds of media are not available:
(1) molten alkali metal solution
(2) hydrofluoric acid under high temperature and high pressure
(3) strong fluoride medium (such as three chlorine fluoride, uranium hexafluoride etc.)
(4) gaseous fluorine and liquid fluorine.
(5) non use on nuclear pipes at nuclear level, nuclear two and nuclear three (reason: PTFE polymer chain structure, nuclear radiation meeting high chain structure)
In order to meet the customers' needs for high quality PTFE gaskets, we have introduced some foreign famous foreign famous brands of expanded teflon and modified tetrafluoro sheet, such as Gore, Garlock, Valqua, TEMAC and other reference expanded teflon plates
The hard expanded teflon plate is used in the industry: chemical, petrochemical, oil refining, chlor alkali, acid, phosphate, pharmaceutical, pesticide, chemical fiber, dyeing, coking, gas, organic synthesis, nonferrous smelting, steel, atomic energy and high purity products (such as ion membrane electrolysis), heavy material delivery and operation, and high strict hygienic requirements Food, beverage and other processing and production departments.
ZD-GS1620 is suitable for high pressure and high temperature, all kinds of fluid under hard working conditions, strong acid, strong alkali, gas, solvent, hydrocarbon, water, chlorine, aluminum fluoride, hydrogen oxide and so on. It has good performance in petrochemical, caustic soda, chlor alkali, shipbuilding and other industries.
Use equipment: pipe, valve, pump, pressure vessel, heat exchanger, condenser, generator, air compressor, exhaust pipe, refrigerator and other flange connection parts
