　　Shielding heat shrinkable tube has multiple functions such as structural connection, insulator, protection, identification, etc. It is widely used in the fields of covering and insulation protection of wire processing, solder joint protection, covering of electronic parts, wire marking or color marking, etc.　

　　What is Heat Shrink Tubing?

　　Heat-shrinkable tube is a new type of environmentally friendly halogen-free flame-retardant sleeve. It is generally made of high-quality soft cross-linked polyolefin material on the outside, and the inner layer of hot-melt adhesive is compounded. There are various types of PVC, PET pipes, and adhesives.

　　2. What is the function of the shielding heat shrinkable tube?

　　Shielded heat shrinkable tubes are protective tubes with special functions of heat shrinkage, which are very common in many fields in industry, electricity, and life. It mainly plays the role of protecting the contained things (mainly: insulation, flame retardant, anti-corrosion, etc. protection). It is mainly used in electricity, as well as in the electronics industry.

　　Since the material is made of cross-linked polyolefin, the strength of the cross-linked molecular bonds determines the type selection. If the degree of cross-linking is not high, you can choose a product filled with recycled materials. Due to the use of plasticizers, it can imitate The product performance of the raw material, but the shrinkage rate is not high, and the shrinkage force (the molecular bond is not strong) is not enough.

　　1. Structural connection

　　The shielding heat shrinkable tube can be used to improve the connection between the electrical connector and the wire. After the wire and the electrical connector are connected, the heat shrinkable tube can be put on for heat shrinkage. This can improve the connection tensile strength, electrical equipment performance and airtightness at the connection position, thereby providing better safety protection for the wires.

　　2. Use an insulator

　　The insulators on the outer surface of many terminals are not only complex in shape, but also thin in wall thickness, so the plastic mold of this insulator is difficult to manufacture. Using shielded heat shrinkable tubes can solve this problem, and the insulation performance is very good, so it can be used as an insulator.

　　3. Protective effect

　　Shielded heat shrink tubing has the characteristics of insulation protection, electrical insulation, weather resistance, anti-aging, etc. It can be widely used in the fields of cable insulation protection, insulation treatment or stress relief at ends or connections, and has a good protective effect.

　　4. Identification function

　　There are many appearances of shielding heat shrinkable tubes, and different colors can be used in different places. They have a relatively clear display function and can represent different power sources.

　　3. The scope of application of the shielded heat shrinkable tube

　　Widely used in excellent flame retardancy, environmental protection, insulation performance, temperature, shrinkage, protection of temperature-sensitive components, covering and insulation protection of wire processing, solder joint protection, coating of electronic components, resistors, capacitors Insulation protection, rust prevention of metal products, anti-corrosion treatment, wire marking or color marking, etc.
