Ptfe gasket: with corrosion resistance, aging resistance and non-conductive and other good characteristics of material selection: tetrafluoron powder, tetrafluoron plate temperature: -150-250℃ pressure: 6.4Mpa

【 Main uses 】 High cleanliness medium

Note: When the temperature is below -185℃. Teflon spacers will become brittle. Pure polytetrafluoroethylene gasket is a kind of clean sealing products, will not be in contact with any substance pollution, can be widely used in food, medicine and other industries.

Has a series of excellent performance:

1) High temperature resistance - long-term use temperature of 200 ~ 260 degrees,

2) Low temperature resistance -- -100 degrees;

3) Corrosion resistance -- resistance to aqua regia and all organic solvents;

4) Weather resistance -- good aging life in plastics;

5) High lubrication -- small friction coefficient of plastic (0.04);

6) non-viscous -- has small surface tension of solid material and does not adhere to any substance;

7) Non-toxic -- with physiological inertia;

8) Excellent electrical performance, is the ideal C class insulation material.

Polytetrafluoroethylene (PTFE) is widely used in machinery, automobile, electronics, chemicals, valves and other parts because of its high temperature resistance (260℃), electrical resistance (45KV/mm), strong acid resistance, strong alkali resistance, anti-adhesion, slippery, wear-resistant engineering plastic materials. Teflon hose is widely used in chemical, instrument, electric heating, machinery industry; Insulation bushing because of high temperature resistance, voltage resistance (300V) and widely used in aerospace, automotive, medical, electronic transformers, communications and other technology and industry

Polytetrafluoroethylene is made of tetrafluoroethylene by polymerization of polymer compounds, has excellent chemical stability, corrosion resistance (is one of the best corrosion resistance materials in the world today, in addition to molten metal sodium and liquid fluorine, the ability of all other chemicals, boiling in king water does not change, Widely used in a variety of acid, alkali and organic solvent resistance conditions), sealing, high lubrication non-viscosity, electrical insulation and good aging resistance, temperature span (can work for a long time at +250℃ to -180℃ temperature).

Its birth has solved many problems in chemical, petroleum, pharmaceutical and other fields in the world. It has been widely used as sealing material and filling material.

The uses of fluorine plastics can be summarized as:

1. Take advantage of its drug resistance: The application of pout plastic in drug resistance is no longer limited to the manufacture of seals, gaskets, pipe fittings, and the use of other parts requiring corrosion resistance (such as pipes) is also increasing. With the progress of raw materials and processing technology, the molding method of fluorine plastics and expand the range of factory selection: such as injection molding can greatly improve the production efficiency, small batch production can use cutting processing technology, PTFE bonding and welding technology development makes it possible to manufacture large storage tank and equipment lining, FEP powder spraying process makes processing more flexible and convenient. In the process of semiconductor production, anti-corrosion and anti-pollution have been used more fluorine plastics.

2. Mechanical industry field: PTFE friction coefficient is small, the static friction coefficient is lower than the dynamic friction coefficient, can be used in low speed and high load field, such as in civil engineering, chemical industry, Bridges and other structural parts can solve the thermal expansion and vibration caused by expansion problems.

Specific applications are:

1. Bearing sleeve of anti-pollution machinery (such as textile, papermaking, pharmaceutical, food machinery);

2. Transport alkali, solvent and other non-lubricating liquid machinery (such as blender, dyeing machine, pump);

3. Shaft sleeve working in acid, alkali and other corrosive environment (such as electroplating bath chemical equipment);

4. No oil lubrication (such as oxygen production equipment);

5. Yuan oil lubrication (such as ultra-low temperature refrigerator, liquid fuel pump);

6. The sliding parts working under the environment with poor oil lubrication effect (add high temperature dryer, inside the furnace, inside the furnace conveyor belt);

7. Sliding parts (movable supports) at low speed and high load.

8. Electrical field: fluorine plastics are inflammable materials. High critical oxygen index and corrosion, can be used as a wire insulation layer. ETFElPvDF has high insulation resistance, insulation strength and excellent mechanical strength. qT is used for cables for computers and communication machines. It can be used for small cables in oil Wells and nuclear reactors by its weatherability and radiation resistance. Using its high frequency relative dielectric constant and dielectric loss are low characteristics can be used for communication equipment, high frequency electric instruments, PTFE and carbon black, carbon fiber such conductive materials can be mixed as anti-static materials and heating components. PvDF can also be made into piezoelectric components for the radio industry and instrument industry.

9. Non-stickiness: Kitchen equipment (such as non-stick pan, snack mold), exterior wall coating of senior buildings, foam molding mold, copier roller, etc., can be manufactured by using the non-stickiness of fluorine plastics. In addition, it is increasingly widely used in artificial blood vessels, heart flap and other medical soil engineering materials, gas separation membrane, waterproof and breathable composite fabric and so on.
