1. Teflon heating tube
The commonly used Teflon heating tube is a new type of strong corrosion-resistant electric heater made of PTFE sleeve, which is used for heating various corrosive liquids. It has excellent aging resistance and good bending performance, and adopts a low surface load design.
There are two types of Teflon heating tubes. One is to spray the surface of the heating tube directly with a fluoroplastic material, and the other is to cover the outer layer of the iron heating tube and the copper heating tube with a fluoroplastic sleeve.
Teflon heaters are electroplating, electrolysis, degreasing, pickling, electroless nickel and phosphorus plating, hydrofluoric acid, anodizing, aluminum, smelting, chemical, pharmaceutical, food and other corrosive liquid heating, condensation, evaporation, The best heater choice for concentration and more!

Performance of Teflon heating tube:
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 the production operation. 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.
7. Non-toxic: In 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.
2. High temperature resistant insulation and fireproof casing
High temperature resistant insulation and fireproof casing are generally suitable for protecting short or straight pipelines, cable protection, automobile wiring harnesses, and generator sets. They are reliable after installation, not easy to disassemble, and have better sealing, insulation, heat insulation and moisture-proof effects.
Teflon pipes are the most used high-temperature insulating and fire-resistant casing, because Teflon pipes have very beneficial high-temperature resistance and insulation effects. However, I will explain the flame retardant effect in detail to prevent you from misunderstanding during use.
Flame-retardant means that this item is not easy to burn, or will go out by itself after leaving the fire. Let me give you an example. The paper is ready at a point and can be a combustion-supporting agent to help combustion. The paper is not flame retardant.
In order to solve everyone’s questions, I deliberately burned the Teflon tube with a lighter for one minute (the temperature of the yellow flame of the lighter was about 200℃). The Teflon tube did not have any sparks, and there was no flame leaving the fire source. The Teflon tube turns into black powder. Without the temperature of a flame, Teflon can withstand a temperature of 260°C without melting.
Strictly speaking, Teflon tube is flame-retardant and not flame-retardant. According to Baidu's explanation of flame-retardant, "this item is not easy to burn or will go out after leaving the fire." Teflon tube is flame-retardant. But you have to use it as a kind of flame-retardant material, let it become a shield, burn at high temperature, the burning time is too long, it will turn into powder, the shield loses its protective function, and the Teflon tube will not achieve the flame-retardant effect. . So whether it is flame retardant or not depends on how you use it.
