What is heat shrink tubing?

   To figure out what a heat shrinkable tube is, you can understand it based on its name. In layman's terms, it is: a plastic sleeve that can shrink when exposed to heat, so it is also called a heat shrinkable sleeve, heat shrinkable sleeve, Heat shrinkable tubes, in fact, they are essentially the same product, collectively called heat shrinkable tubes. Because of its thermal shrinkage characteristics, it is an indispensable and important protective pipe in various industries. The inner diameter specifications are very complete, from the smallest diameter of 0.5mm to the largest diameter of 250mm. The colors can also be diversified. The conventional red, orange, yellow, green, blue and purple are all available, and the audience is also very wide. Heat shrinkable tubes are usually made of soft materials, and the heat shrinkage ratio can reach 2 times, which means that a heat shrinkable tube with a diameter of 6mm can be heated The diameter after shrinkage can be reduced to 3mm.

    Heat shrinkable tubing has been recognized by many developed countries since the 1960s, mainly benefiting from the rapid development of the automotive industry and home appliance industry. In the 1970s, heat shrinkable tubes developed rapidly and heat shrinkable materials began to be industrialized. Domestic research and development of heat shrinkable tubes was also very early. After nearly half a century of rapid development, the quality stability of heat shrink tubes has also been effectively improved, so heat shrink tubes are now also ridiculed as special band-aids for industry, electrical appliances, machinery, high-speed rail, and automobile cable lines. Why can heat shrink tube be called a cable line band-aid? The main reasons are as follows:

1. Cable connection

    Heat shrinkable tubes can be used to connect the wire welding points. When the wires are welded, the exposed solder joints leak in the air, which is a safety and quality hazard. In order to enhance the tensile strength of the connection position and provide better safety protection for the wires , you can use heat shrink tubes at the welding points to improve tensile strength and safety, which also indirectly improves quality reliability and avoids safety hazards.

2. Insulation protection

     Terminal blocks are very common in electrical equipment. After the wires and terminal blocks are welded, a long part of the conductor leaks out. In fact, only the circle of conductors that need to be screwed is exposed. If the injection molding process is used, the cost will be very high. Expensive, because heat shrinkable tubes have good insulation properties, so we can use heat shrinkable tubes to solve this problem.

3. Protective effect

     The physical properties of heat shrinkable tubes are very excellent, with electrical insulation properties and aging resistance. It can be widely used in various industries for cable insulation protection, insulation protection and stress relief at wiring ends and cable connections. It can play a very good role. Protective effects.
