  1. Special Teflon heat-shrinkable tubing for medical equipment

  Teflon heat shrink tubing for medical equipment

  Product description: Teflon heat-shrinkable tube is made of high-quality PTFE material extruded and expanded, which has outstanding wear resistance, oil resistance, chemical corrosion resistance and high temperature performance. It is suitable for occasions requiring high temperature, and is used for insulation protection and pressure relief of connection welding and area identification of covered components.

  Teflon heat-shrinkable tubing for medical equipment application: -80℃--300℃, starting shrinkage temperature of 280℃, suitable for occasions requiring high temperature, the product is mainly used for insulation protection and pressure relief of connection welding and covering components Area identification, as well as electronics, medical, aviation, military and other aspects.

  2. Teflon tube for mold temperature machine

  The main purpose of the mold temperature machine is to heat the mold to speed up the production schedule. The mold temperature machine can control the mold temperature more uniformly, improve the molding efficiency of the product, reduce the occurrence of defective products, improve the appearance of the product, resist product defects, speed up the production schedule, reduce energy consumption and save energy.

  Mold temperature controllers are widely used in plastic molding, light guide plate die-casting, rubber tires, automotive interior parts, rollers, biopharmaceuticals, chemical reactors, bonding, banburying and other industries. It is environmentally friendly, energy-saving, fast and safe, with high heat source utilization, no manual operation, and cyclic temperature control. With the reduction of traditional limited energy and the increase of market demand, mold temperature controllers are becoming more and more recognized by everyone as a new heat source providing equipment.

  Because the mold temperature machine has the function of temperature control, the Teflon tube comes in handy.

  Teflon performance:

  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.

  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 and high insulation.

  Three, the role of 3D printer Teflon tube

  3D printers have a historical headache, which is easy to plug! Many people guess that the temperature of the throat is too high, so many manufacturers now switch to the throat with built-in Teflon. The thermal conductivity of Teflon and stainless steel is low. , Can effectively reduce the temperature of the throat, using Teflon throat, the plug failure rate is significantly reduced.

  Due to the excellent performance of Teflon, it is currently used in a wide range of applications. It can be used for pipeline anti-corrosion, high and low temperature resistance, and corrosion resistance. Used in harsh environments such as lubrication, electronics, electrical appliances, aerospace, and medical treatment.
