Analysis of flame retardant characteristics of heat shrinkable tube

Heat shrinkable tubing is an indispensable new material product in the current industrial system. It is widely used in all walks of life, especially in the fields of automotive wiring harnesses, motors, electrical appliances, and complete sets of equipment. In order to improve labor productivity, while heat shrinkable tubes are continuously enhancing the advantages of use, the members of the Heat Shrinkable Tube family are also growing. Today we will not introduce different types of heat shrinkable tube products one by one. We only focus on heat shrinkable tubes. The flame retardant performance of the pipe is introduced.

1. Non-flame retardant heat shrinkable tube: Everyone knows that the main material for producing heat shrinkable tubes is polyethylene. If no flame retardant is added to the heat shrinkable tube during the production process, the produced heat shrinkable tube products are non-flame retardant. Heat-shrinkable tubes, such sleeves have no flame-retardant performance at all, but the environmental protection performance meets the standard, and they are halogen-free heat-shrinkable tubes.
2. VW-1 Flame Retardant Heat Shrink Tube: VW-1 grade casing is added with a flame retardant when mixing materials in the previous process of production, so that the heat shrinkable tube reaches the flame retardant standard of VW-1 grade, and has passed the authority of the first The strict test of the three parties, the qualified product is the VW-1 flame retardant heat shrinkable tube.
3. V0 heat-shrinkable tube: The flame retardancy of V0 heat-shrinkable tube theoretically surpasses VW-1 level. V0 is mainly aimed at stricter requirements for raw materials, and VW-1 is aimed at product testing. There is no difference in the actual use effect of the two. obvious.
The outer material of the heat-shrinkable tube has the characteristics of insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, waterproof sealing and high adhesion. It is often used in the sealing, insulation and protection of cables. In this article, we introduced the physical and chemical properties of heat shrinkable tubes. Today we will introduce to you an important aspect of heat shrinkable tubes that is often overlooked by everyone, which is the process performance of heat shrinkable tubes. In many cases, users often do not understand the heat shrinkable tubes. The process technology of the shrinkable tube, in fact, the process performance of the heat shrinkable tube is also one of the key factors affecting the index of the heat shrinkable tube.
Process performance: The process of process and material manufacturing is an important condition for the selection of heat shrinkable tubes. The installation process should be as simple as possible to facilitate on-site construction. The technical requirements for workers are not high, and the working environment is not picky. The installation quality is controllable and reliable. .
The reliability of heat shrink tubing can be judged and purchased from five aspects: electrical performance, sealing performance, mechanical performance, chemical performance, and process performance. As a common insulating sleeve, the heat shrinkable tube is fully competent, fully meets the above five requirements, and is the best choice for cable protection. The corresponding problems can be solved by using heat-shrinkable tubes. To purchase heat-shrinkable tubes.
