High quality PTFE Casing is made of suspended polytetrafluoroethylene resin and extruded by plunger. Among the known plastics, polytetrafluoroethylene has better chemical resistance and dielectric properties. It can be used for insulating sheath of electric wire and corrosive fluid medium pipeline. There is still a lot of knowledge about high quality PTFE casing. Next, it introduces the advantages of PEFE casing. High quality PTFE casing has excellent high and low temperature resistance, and high quality PTFE casing has excellent high and low temperature resistance. It can be used for a long time at - 80-250 ℃: weather resistance, fire resistance, high oxygen index, no water absorption, excellent radiation resistance, such as long-term exposure to the atmosphere, can still keep its surface and various properties basically unchanged; excellent dielectric properties, high pressure resistance; Excellent corrosion resistance, almost insoluble in any solvent, strong acid aqua regia, strong alkali concentrated sodium hydroxide, strong corrosive agent uranium pentafluoride will not corrode; good wear resistance, static friction coefficient is relatively small in plastic, excellent self-lubricating performance, special surface non viscosity; good tensile strength characteristics. High quality PTFE sleeve is made of common carbon steel pipe, lined with PTFE material with excellent chemical stability, and formed by cold drawing composite material or roll molding. It has not only the mechanical properties of steel pipe, but also the corrosion resistance of plastic pipe. Slow scaling, not easy to grow microorganisms, is an ideal pipeline for Polytransporting acid, alkali, salt, corrosive gas and other media. High quality Teflon sleeve is a kind of plastic lined pipe. High price, high temperature and corrosion resistance of plastic lined pipes. It is usually used as the pipeline of highly corrosive fluid medium such as strong acid and strong alkali.
The advantages of high-quality PTFE casing are: (1) high-quality PTFE casing has high chemical stability: it can bear all strong acids, including aqua regia, hydrofluoric acid, concentrated hydrochloric acid, nitric acid, fuming sulfuric acid, organic acid, and has the functions of strong alkali, strong oxidant, reducing agent and various organic solvents. It is widely used in the transportation of various irritant liquids. (2) Working temperature range: - 80 ℃ - 280 ℃ can be used for a long time. It works at freezing temperatures without embrittlement and does not melt at high temperatures. (3) Excellent non adhesion: excellent anti adhesion, colloid and chemicals will not adhere to the inner wall of the pipe, so there will be no dirt layer in the pipe. (4) The excellent electrical insulation performance of PTFE is a highly non-polar material with good dielectric properties, large resistance and dielectric constant of about 2.0. It is relatively small of all electrical insulating materials, and its temperature and frequency changes have little impact on them. (5) Excellent aging resistance and radiation resistance: can be used outdoors for a long time. (6) Excellent thermal stability: PTFE has a very valuable non combustibility, its oxygen limit index is higher than 95, it can only melt on the flame, not form droplets, and can only be carbonized. (7) High flexibility and bending resistance (8) moisture resistance: the surface of PTFE coating is free of water and oil, which is not easy to be wetted by solution in the production process. If there is a small amount of dirt, it can be removed by simple wiping. Short downtime saves time and improves productivity. (9) Wear resistance: excellent wear resistance under high load. Under a certain load, it has the double advantages of wear-resistant and non stick.
