As a heat shrinkable tube with high temperature resistance and high mechanical strength, Teflon heat shrinkable tube is widely used. As one of the products with the highest high temperature resistance among heat shrinkable tubes, it can continue to work stably at 260°C for a long time. No deformation softening occurs. Therefore, it is widely used in the insulation protection of bare conductor wire harnesses. Because of its excellent temperature resistance, color development is not so easy during the process of heating and shrinkage, and many problems will be encountered.

   Shrinkage temperature of Teflon heat shrinkable tube. First of all, we need to understand the shrinkage temperature of Teflon heat shrinkable tube. As a heat shrinkable tube manufacturer, we can clearly tell you that the initial shrinkage temperature of Teflon heat shrinkable tube is 350℃. We generally control it at 350-400℃.

   How to heat and shrink Teflon heat shrink tubing quickly? After figuring out the shrinkage temperature of Teflon heat shrink tubing, it becomes very simple to know how to heat and shrink Teflon heat shrink tubing quickly. Sharpen the knife without chopping firewood, and understand the shrinkage of Teflon heat shrink tubing. method, you can heat and shrink quickly.

1. First, adjust the temperature of the hot air gun to 400°C. You may ask why it is not 350°C. Because we cannot deviate from our theme, we have to heat and shrink quickly, plus heat energy loss, so the temperature is adjusted higher.

2. When starting to heat and shrink, be sure to rotate the Teflon heat shrink tube around the axis. Do not heat only one place, otherwise uneven shrinkage will occur. After this circle is completely shrunk, the entire circle becomes transparent and begins to move longitudinally. Repeat the rotation and heating of the Teflon heat shrink tube around the axis until it is completely shrunk. Remember not to use too high a local heating temperature and keep heating to one location. It is normal for Teflon heat shrink tubing to turn white after being removed from the heat source.

3. Check the effect after shrinkage. A qualified Teflon heat shrink tube must be flat, smooth and without creases, and it should fit perfectly with the product being protected, without any bulging.

   As long as the corresponding temperature is adjusted, it can shrink quickly. If there is no heat gun, baking with a lighter will be very slow, the heating will be uneven, and it will not achieve good results. How to heat and shrink Teflon heat shrink tube quickly? , it’s actually very simple, just adjust the temperature to 400℃, it can shrink quickly, and the effect is very good.
