  1. Ozone resistant Teflon tube

  Ozone is a broad-spectrum bactericide, which can kill bacterial propagules and spores, viruses, fungi, etc., can destroy botulinum toxins and toxins, and Rickettsia Stink and other peculiar smell function. Ozone sterilizes faster in water than chlorine. From the perspective of the development history of ozone, the application of ozone can be divided into four fields: water quality treatment, chemical oxidation, food processing and preservation, and medical treatment. The application research and equipment development in each field have reached a very high level.

  What kind of pipeline is used to transport ozone?

  At present, the most used and most effective ozone-resistant tube on the market is Teflon tube.

  PTFE Teflon pipe

  Teflon (also known as polytetrafluoroethylene, PTFE), it has the characteristics of resistance to acid, alkali, and various organic solvents, and it is almost insoluble in all solvents. At the same time, PTFE has the characteristics of high temperature resistance, its friction coefficient is extremely low, and it is an ideal material for chemical solvent-resistant transportation pipelines. Among the grades of ozone-resistant materials, Teflon belongs to the A-Excellent grade.

  Let me introduce the detailed characteristics of the ozone-resistant Teflon tube and tell you why it is so excellent.

  1. Non-sticky: Teflon is inert, almost all materials are not bonded with Teflon, and the thin film also shows non-stick performance.

  2. Heat and cold resistance: Teflon has excellent heat and low temperature resistance. In a short time, it can withstand temperature to 300℃, melting point is 327℃, and it will not melt at 380℃. Generally, it can be used continuously between 240℃ and 260℃. It has remarkable thermal stability. It can work at freezing temperature. No embrittlement, cold resistance to 190℃.

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

  4. Non-hygroscopicity: The surface of Teflon does not stick to water and oil, and it is not easy to stick to the solution during production operations. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving working hours and improving work efficiency.

  5. Corrosion resistance: Teflon is hardly 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 oxidants, reducing agents and various organic solvents can protect parts from any kind of chemical corrosion.

  6. Weather resistance: non-aging, the best non-aging life among plastics.

  2. Large-caliber Teflon heat-shrinkable tube

  Large-caliber Teflon heat-shrinkable tubing has the characteristics of high temperature resistance, corrosion resistance, high pressure resistance, flame retardancy and long-term non-aging.

  Widely used in aerospace, instrumentation, textile and chemical industry, food and medical, electronic appliances, post and telecommunications, petrochemicals, metallurgical electronics, railway transportation, electrical appliances, household appliances, high-rise buildings, lighting, special transformers, special cables, sensors , Thermal components and other industries.

  Features of large diameter Teflon heat shrinkable tube:

  1. The shrinkage ratio is 1.7:1 or 4:1

  2. High flame retardant, good toughness, excellent physical properties and chemical corrosion resistance

  3. It does not contain chlorine compounds PCBS, PCPS, polybrominated biphenyls PBBs, polybrominated oxide biphenyls PBBOs, polybrominated diphenyl ethers PBBEs, PBDEs and other substances that are harmful to the environment, and meets the environmental protection requirements of European RoHS environmental protection directives and standards.

  4. Temperature range of large diameter Teflon heat shrinkable tube

  Continuous use temperature: -55~280

  Minimum initial shrinkage temperature: 260

  Minimum full shrinkage temperature: 300
