As a manufacturer of level meters and liquid level instruments, we are certainly familiar with PTFE material. When I first joined the industry, I also searched the website many times, such as, what is PTFE material? What is PTFE material? What is the material of ferrite? And so on these questions, now let me introduce you to it.

In fact, the simple answer is that PTFE is a plastic, is a good performance plastic, people call it "plastic king" . Ptfe level sensor material is different from other plastic performance, processing methods, etc.. PTFE material performance can be used for artillery shells and other anti-melt sealing gaskets, so after DuPont invented this technology, the U.S. military will be the technology has been closed to the public during World War II, until the end of World War II, only then gradually achieve industrial production of PTFE material, so many companies want to understand this PTFE material, because PTFE material has many good characteristics, PTFE material use has become more and more. PTFE materials have been used more and more.

PTFE is the abbreviation of Poly tetra fluoroethylene (Poly tetra fluoroethylene), is a kind of engineering plastics, PTFE chemical name called poly tetrafluoroethylene. Teflon is the alias of polytetrafluoroethylene, many foreign friends also called Teflon, because Teflon is the registered trademark of DuPont, polytetrafluoroethylene plastic is invented by the United States DuPont, so many people later called it Teflon, Teflon. Teflon is the common name of polytetrafluoroethylene, which is the registered trademark of DuPont, called Teflon, English polytetrafluoroethylene.

PTFE performance.

1, good corrosion resistance, can withstand in addition to molten alkali metal fluoride medium and above 300 ℃ sodium hydroxide in addition to all strong acids, strong oxidizing agents, reducing agents and a variety of organic solvents;

2, has a strong insulation resistance, not affected by the environment and frequency, volume resistance up to 1018 Ohm-cm, small dielectric loss, high breakdown voltage;

3, has excellent resistance to high and low temperature, the influence of temperature does not change much, the temperature range is wide, can use the working temperature -190 ℃ ~ +250 ℃;

4, PTFE material has a unique self-lubricating, with a smaller coefficient of friction in plastic, is the ideal oil-free lubrication material, can be used as oil-free bearings, etc.;

5, has outstanding surface non-stick, is a solid material with small surface energy;

6, PTFE material also has good resistance to atmospheric aging, resistance to amplitude radiation performance and low permeability, long-term exposure to the atmosphere, its surface properties remain unchanged;

7, PTFE material is non-combustible, the oxygen limit parameter is below 90, such as the open flame removed, PTFE material will not continue to RS. But it is worth noting that although PTFE material is non-toxic, safe, such as in 380 ℃ or above the high temperature or encounter open fire, high temperature cracking can release toxic gases, which is to pay attention to

Applications of PTFE

Because PTFE material has the above characteristics, so it has a wide range of uses, usually made of PTFE plate, PTFE tube, PTFE rod, PTFE film, a variety of shaped zero any, can also be used to push extrusion or extrusion processing molding, for high-temperature wire, but also can be made into a film and then slit into the axis of PTFE wrapped tape, used in the production of high-frequency cable or directly made of water dispersion, then can be used for coating, impregnation or made of fiber; in addition, we often see the non-stick pans are made of PTFE non-stick material, food and other industry sectors to grab the bottle machine parts and plastic mouth, Impregnated or made of fiber; In addition, we often see the non-stick pans is the use of PTFE non-stick material to build, food and other industry sectors to grab the bottle machine parts and plastic mouth. Various PTFE products have played a pivotal role in the chemical industry, machinery, electronics, electrical appliances, aerospace, light industry, textile, environmental protection and bridges and other areas of the national economy.

    I take you to see, our company produces the level meter in what specific applications, such as radio frequency conductivity level meter corrosion part, rf capacitance level sensor corrosion part, radar level meter corrosion part, corrosion-resistant magnetic flap level meter is PTFE as the liner, ultrasonic level meter corrosion part, tuning fork level meter corrosion coating, etc., are used PTFE material In short, PTFE materials are becoming more and more irreplaceable in various industries.
