‍Teflon heat shrinkable tube with its unique advantages of high temperature resistance and high mechanical strength in the market by many industry users continue to use, often used for cable insulation protection. However, although the domestic professional teflon heat shrinkable tube can withstand the high temperature of more than 100 degrees Celsius, but in the actual use of the teflon heat shrinkable tube heating, and can not be simple and rough, but also need users to pay attention to the following three aspects.‍

First, pay attention to the control of heating temperature

Teflon heat shrink tube is usually produced by polymer materials through special technology, usually in a short time of high temperature environment will not have an impact on its performance and appearance, but for local long-term high temperature heating teflon heat shrink tube will be damaged or burned, so in the actual process of processing, It is necessary to control the local heating temperature of teflon heat shrinkable tube, which can effectively improve the service life of the product.

Two, pay attention to preheat in advance

Usually, the operator needs to ensure the tightness and adhesion between the teflon heat shrinkable tube and the packaging material when the operation is carried out between the teflon heat shrinkable tube and the packaging material. Therefore, the teflon heat shrinkable tube needs to be pre-heated before the operation, and the tightness and adhesion of the product can be improved by the principle of thermal expansion and cold contraction. It can make the interlayer contact between Teflon heat shrink tube and wrapping material more tightly.

Three, pay attention to the effect of heating

After heating the teflon heat shrink tube, the operator should carefully check whether the heating effect of the teflon heat shrink tube is ideal. The ideal heating effect should be manifested as smooth appearance of the Teflon heat shrink tube without creases, and the outline and structure of the teflon heat shrink tube oil can be clearly seen. In addition, pay attention to whether there is a small amount of sealant leakage in the injected part of the sealant, and then a small amount of sealant overflow to show that the sealing degree is good.

The heating of Teflon heat shrink tube with moderate price needs to be operated by staff with certain operating experience. In addition to the above three points for attention, the rich experience of the operator is also very important when heating. Some problems may not have obvious signs, but experienced staff are often able to keenly feel which parts may have problems. Can effectively avoid teflon heat shrinkable tube heating damage.
