　　In our daily life, there are many household appliance wires, and it is risky to directly touch such wires. Generally, everyone's practice is to encapsulate a layer of heat-shrinkable tube on some dangerous-level power circuits or wires. The shielding heat shrinkable tube can not only play the role of insulation, but also greatly reduce the risk of electric shock accidents in people's lives. So today we will talk about the use of shielding heat shrinkable tubes .　　

　　Uses of shielded heat shrink tubing:

　　1. The shielding heat shrink tube is made of special raw materials and has the function of heat shrinkage. On power circuits it is used to be able to plug in a damaged wire or two. It can play the role of maintenance, heat preservation, moisture resistance and high temperature shrinkage.

　　2. It can also repair broken wires. You can use a ruler to measure the length of the damaged switching power supply, and cut off the same length of heat shrinkable tube. Then, insert the damaged power plug into the heat shrink tube, adjust the middle and the damaged power plug. Then, the key part is to bake symmetrically back and forth with a lighter so that it is heated tightly.

　　3. In addition to repairing wires, it is often used to fuse two wires or special tools in daily life. Before fusing, the shielding heat shrinkable tube must be placed in one of the wires that must be fused, and then the two pieces of wire are coiled, moved to the joint and heated with fire to make it shrink, which can be easily pieced together.

　　The double-wall shielded heat-shrinkable tube is produced by a double-layer pneumatic process of polyolefin and other halogen-free cathode fuels and hot-melt adhesives. The outer layer has the characteristics of polyolefin insulation, halogen-free flame retardant, and low temperature shrinkage. The inner layer has the advantages of low melting point, good adhesion, waterproof sealing and mechanical buffering.

　　Applied to:

　　1. Functional use: wear-resistant, anti-leakage, sealing and waterproofing of multi-strand wire bundles, anti-corrosion protection, and anti-ultraviolet rays.

　　2. Application fields: Electronic equipment, home wire bundles, automobile wire bundles, wires and cables, metal pipes, pumps, submersible pump wiring and waterproofing industries.

　　Shielding heat shrinkable tubes obviously surpass PVC in terms of heat resistance, electrical insulation, and mechanical properties. More importantly, PET is non-toxic, easy to recycle, better meets environmental requirements, and has no toxic effects on the human body and the environment.
