High temperature acid and alkali resistant PTFE tube

PTFE tube is a special kind of tube made by extrusion and sintering of PTFE material, which is made by drying and high-temperature sintering and fining and other processes. It is widely used in mechanical, electronic, automotive, aerospace, chemical industry, computer, electric heating, military communication and other important scientific and technological industries, such as miniature transformer, etc

PTFE tube feature

1. High chemical stability, able to bear all the strong acid, including aqua regia hydrofluoric acid concentrated nitric acid fuming sulfuric acid hydrochloric acid organic acids, such as alkali strong oxidizer reducer and the role of various kinds of organic solvent is very suitable for high purity chemical feed use

2. Low coefficient of friction, the friction coefficient is generally only 0.04, is a very excellent self-lubrication material, and the friction coefficient does not change with temperature change

3.Viscous resistance is good, the inner wall of the tube is not easy to stick colloid and chemicals

4.Excellent aging resistance, can be long-term in outdoor use

5.Excellent electrical insulation performance :PTFE is a non-polar material with high height, good dielectric property, great resistance and dielectric constant of about 2.0. Among all electrical insulation materials, the smallest

6.Parts have high transparency and can easily observe the internal fluid condition

The performance of PTFE pipe:

1. Non-adhesiveness: PTFE is inert, almost all substances are not bonded to PTFE, and very thin films also show non-adhesive properties.

2. Cold and heat resistance: PTFE has excellent heat resistance and low temperature resistance. It can withstand temperature up to 300°C in a short period of time, with a melting point of 327°C and does not melt at 380°C. Generally, it can be used continuously between 240°C and 260°C. It has remarkable thermal stability, and it can work at freezing temperatures. Not brittle, cold-resistant to 190°C.

3. Lubricity: PTFE has a low coefficient of friction. The friction coefficient changes when the load slides, but the value is only between 0.04-0.15.

4. Non-hygroscopicity: The surface of PTFE is not stained with water and oil, and it is not easy to be stained with solution during production and operation. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime saves man-hours and improves work efficiency.

5. Corrosion resistance: PTFE is almost not corroded by chemicals, and can withstand all strong acids (including aqua regia), strong alkalis, and strong acids except molten alkali metals, fluorinated media, and sodium hydroxide above 300 °C The role of oxidizing agents, reducing agents and various organic solvents can protect parts from any kind of chemical corrosion.

6. Weather resistance: no aging, no aging life in plastics.

7. Non-toxic: In the normal environment within 300 ℃, it is physiologically inert, non-toxic and can be used as medical and food equipment.

8. Insulation: very good dielectric constant, high insulation.

The Application of PTFE tube:

The full name of PTFE in English is Polytetrafluoroetylene, referred to as PTFE, PTFE, F4, etc. PTFE (Polytetrafluoroethene) is a synthetic polymer material that uses fluorine to replace all hydrogen atoms in polyethylene. This material is resistant to acid and alkali, and various organic solvents, and is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, and its friction coefficient is extremely low, so it can be used for lubrication, and it has also become an ideal coating for the inner layer of easy-cleaning woks and water pipes. It can be used for pipeline anticorrosion, high and low temperature resistance, and corrosion resistance. Lubrication and other engineering, electronics, electrical appliances, aviation and other harsh environments.
