Introduction of Expanded sheet sheet ！

Performance characteristics of hard expanded teflon plate:

1. 100% pure polytetrafluoroethylene, good chemical resistance.

2. The molecular structure is multidirectional arrangement. In addition to all the advantages of ordinary tetrafluoro, it also has cold flow resistance and creep resistance.

3. It can be used to seal interfaces with different hardness.

(1) Rigid metal interface (generally 3mm)

(2) FRP interface (generally 3mm)

(3) Plastic lining interface (used below DN300 caliber)

(4) Tangci, used on steel lined glass interface.

4. Zd-gs1620 has good leakage resistance, and the gas leakage rate is 1 × Below 10-4, it can be used for the sealing of corrosive gases, such as chlorine, vinyl chloride, etc., to help many large caustic soda plants and chlor alkali plants solve the leakage of chlorine and other gases. It is the only high-performance domestic material with two uses of chlorine in China, and has a good reputation in the chlor alkali industry.

5. Zd-gs1620 hard expanded teflon plate is a turning plate with good flatness.

6. The following five media are not available:

(1) Molten alkali metal solution

(2) Hydrofluoric acid under high temperature and high pressure

(3) Strong fluorinated medium (such as chlorine trifluoride, uranium hexafluoride, etc.)

(4) Gaseous fluorine, liquid fluorine.

(5) Nuclear level I, nuclear level II and nuclear level III equipment cannot be used on nuclear pipelines (reason: polymer chain structure of polytetrafluoroethylene, high chain structure of nuclear radiation impact section)

In order to meet the needs of customers for high-quality PTFE gaskets, we have introduced some foreign famous brands of expanded PTFE plates and modified PTFE plates with excellent performance, such as Gore, Garlock, valqua, temac, etc., which can be referred to as expanded PTFE plates

Industries using hard expanded tetrafluoro plates: chemical, petrochemical, oil refining, chlor alkali, acid making, phosphate fertilizer, pharmaceutical, pesticide, chemical fiber, dyeing, coking, coal gas, organic synthesis, non-ferrous smelting, steel, atomic energy and high-purity product production (such as ion-exchange membrane electrolysis), viscous material transportation and operation, food, beverage and other processing and production departments with highly stringent health requirements.

Zd-gs1620 is applicable to various fluids under high pressure and temperature and harsh sealing conditions, such as strong acids, strong alkalis, gases, solvents, hydrocarbons, water, chlorine, aluminum fluoride, hydrogen oxide, etc. it has good performance in petrochemical, caustic soda, chlor alkali, shipbuilding and other industries.

Equipment used: sealing parts at flange connections of pipes, valves, pumps, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerators, etc
