Teflon tubes and Teflon heat shrinkable tubes have a wide range of applications. Specific as follows:
Teflon Heat Shrink Tube for 1. Medical Devices
Product description: Teflon heat shrinkable tube is made of high quality PTFE material, which has outstanding wear resistance, oil resistance, chemical corrosion resistance and high temperature performance. It is suitable for the occasion where high temperature is required, for the insulation protection and pressure relief of the connection welding place and the area identification of the covered components.
Application of Teflon heat shrinkable tube for medical devices:-80 ℃ -300 ℃, starting shrinkage temperature 280 ℃, suitable for occasions requiring high temperature. The products are mainly used for insulation protection, pressure relief and area identification of covered components at welding joints, as well as electronics, medical treatment, aviation, military industry, etc.

Teflon tube for 2. mold temperature machine
The main purpose of the mold temperature machine is to heat the mold and speed up the production schedule. The mold temperature machine can control the mold temperature more evenly, improve the molding efficiency of the product, reduce the production of defective products, improve the appearance of the product, resist the defects of the product, speed up the production schedule, reduce energy consumption and save energy.
Mold temperature machine is widely used in plastic molding, light guide plate die-casting, rubber tires, automotive interior parts, rollers, bio-pharmaceutical, chemical reaction kettle, bonding, mixing and other industries. Its environmental protection, energy saving, fast, safe, high utilization rate of heat source, no manual operation, cycle temperature control, etc. With the reduction of traditional limited energy and the increase of market demand, mold temperature machine as a new heat source to provide equipment more and more recognized by everyone.
Because the mold temperature machine has the function of temperature control, Teflon pipe is of great use.
the performance of teflon:
1. Non-stick: Teflon is inert, almost all substances are not bonded to Teflon, and very thin films also show non-adhesive properties.
2. Cold and heat resistance: Teflon has excellent heat resistance and low temperature resistance. Short time temperature resistance to 300 ℃, melting point of 327 ℃,380 ℃ does not melt, the general work can be used continuously between 240 ℃ ~ 260 ℃, with significant thermal stability, it can work at freezing temperature without embrittlement, cold resistance to 190 ℃.
3, lubricity: Teflon has a lower coefficient of friction. The friction coefficient changes when the load slides, but the value is only between 0.04 and 0.15.
4. Non-hygroscopicity: Teflon surface is not stained with water and oil, and it is not easy to be stained with solution during production operation. If there is a small amount of dirt, it can be removed by simple wiping. Short downtime saves man-hours and improves productivity.
5, corrosion resistance: Teflon is almost not subject to chemical erosion, can withstand in addition to molten alkali metal, fluoride medium and above 300 ℃ sodium hydroxide outside all strong acid (including aqua regia), strong alkali, strong oxidant, reducing agent and a variety of organic solvents, can protect parts from any kind of chemical corrosion.
6. Weather resistance: no aging, the best non-aging life in plastics.
7, non-toxic: 300 ℃ within the normal environment, with physiological inertia, non-toxic can be used for medicine and food equipment.
8, insulation: very good dielectric constant, high insulation.

3. the role of 3D printer Teflon tube
3D printers have a historic legacy of headaches, 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, which can effectively reduce the temperature of the throat. With Teflon throat, the failure rate of the plug is significantly reduced.
Due to the excellent performance of Teflon, it is currently widely used and can be used for pipeline anti-corrosion, high and low temperature resistance, and corrosion resistance. Lubrication and other engineering, electronics, electrical appliances, aerospace, medical and other harsh environments.
