　　With the gradual development of science and technology, the manufacturing industry is developing towards globalization, informatization and automation. People not only care about the production efficiency in modern production and life, but also care about the labor intensity and the comfort of the labor process. With the improvement of the quality of life, the application of heat shrinkable tubes in production and life is also increasing.

　　The role of shielding heat shrinkable tube

　　The shielded heat shrink tube has the characteristics of softness, easy shrinkage at high temperature, non-combustibility, heat insulation and anti-rust. Heat shrinkable tubes can be used for various wiring harnesses, brazing, insulation protection of inductors, rust prevention and corrosion protection of metal tubes and bars, etc. Depending on the temperature, the polymer material changes from low temperature to high glass state-high elastic state, the glass state is close to the performance of plastic, and the high elastic state is close to the performance of rubber. The material used in the shielding heat shrinkable tube is in a glass state under the greenhouse, and becomes a high elastic state after heating.

　　During production, the shielded heat shrinkable tube is heated to a high-elastic state, and a load is applied to expand it, and it is cooled rapidly while maintaining expansion, so that the time period enters a favorable state, and this state is fixed.

　　Classification of shielded heat shrink tubing:

　　1. The shielded heat-shrinkable tube has a special function of heat shrinkage, and it can be shrunk when heated above 98°C, which is easy to use. It can be used instead of various rechargeable batteries for groups, combination packaging, design, printing patterns and tailoring by customers. Covers for all kinds of curtains, shower curtains, mops, mops, broom handles, tool bars, stretches, garden tools, poles and other tubular items. Low-voltage indoor passenger car copper bars, connectors, signs of wiring harnesses, and insulating covers can be used. Reduce equipment investment and reduce integration costs Lamp decoration, LED needle cover, others, and the cover of the bottle mouth are a new generation of packaging materials. Civilian, vehicle, and military are all merchant ships.

　　2. The outer layer of the adhesive-containing double-wall heat-shrinkable sleeve is made of polyethylene alloy, and the inner layer is compounded with hot-melt adhesive. After molding, cross-linking is investigated by an electron accelerator, and continuous expansion is performed. The outer layer has the advantages of softness, low temperature shrinkage, insulation, anti-corrosion, and wear resistance, and the inner layer has the advantages of melting point, adhesion, waterproof sealing, and mechanical variation buffer performance. Waterproof and windproof wiring of electronic equipment, sealing and waterproofing of multi-strand wire bundles (such as household wires, automobile wire bundles, etc.), sealing and waterproofing of wire branches, anti-corrosion protection of metal pipes, wire and cable maintenance, water pump, submersible pump wiring.
