　　Manufacturers of military heat shrinkable tubes : What are the standards and technical requirements for heat shrinkable tubes?

　　According to the market demand and the application environment of products that meet various requirements, heat shrinkable tubes have various models and specifications, and are classified according to different materials and different places of use, causing many users to have no way to start when they first contact and purchase. Tube manufacturers analyze the standards and technical requirements of heat shrinkable tubes in detail.

　　1. Heat shrinkable tube standard

　　As the main auxiliary material for insulation safety protection in industries such as electronic appliances and high-voltage insulation, military heat shrinkable tube manufacturers tell you that heat shrinkable tubes are not currently included in national standards, and now only follow industry standards, which are clearly proposed by the Federation of Electric Power Enterprises. The national standard is cost-effective, mainly due to the difference in the main parameters, and the industry standard also has a very high reference value. Heat shrinkable tubes are widely used in household appliances, so the environmental protection requirements are high.　　

　　Second, the technical requirements of heat shrinkable tube

　　Military heat-shrinkable tube manufacturers: The technical requirements of heat-shrinkable tubes mainly include five main parameters: flame retardant grade, shrinkage rate, rated voltage, working temperature, and wall thickness.

　　1. Heat-shrinkable tubes are divided into flame-retardant and non-flame-retardant types. For example, transparent heat-shrinkable tubes made of PE polyethylene are non-flame-retardant. When purchasing, you must clarify with the heat-shrinkable tube manufacturer whether there are flame-retardant requirements , The flame retardant grade of the heat shrinkable tube is VW-1. It goes out within 60 seconds after leaving the fire source.

　　2. The shrinkage rate is an important technical indicator of the heat shrinkable tube. The shrinkage rate generally refers to the ratio of the shrinkage aperture of the heat shrinkable tube. The shrinkage rate of the traditional heat shrinkable tube is 2, 3, 4 and 6 times.

　　3. Remove the heat-shrinkable tube of the busbar. The rated voltage of other types of heat-shrinkable tubes is usually 600V, and the rated voltage of the busbar heat-shrinkable tubes is divided into 1KV, 10KV, and 35KV.

　　4. According to different models and materials, the working temperature ranges from 105 to 260. The rated working temperature of the transparent heat shrinkable tube is 105. The conventional heat shrinkable tube is 125. The military standard heat shrinkable tube is 135. The PVDF heat shrinkable tube is 150 To 175. Rubber heat shrink tube is 200. Teflon heat shrink tube is 260.

　　5. The wall thickness is easy to understand. The heat shrinkable tube industry usually refers to the single-sided wall thickness. The wall thickness of the single-wall heat-shrinkable tube is usually about 0.3-1mm after fully shrinking, and the wall thickness of the double-wall heat-shrinkable tube is 0.8mm after fully shrinking. -1.5mm or so, thick-walled heat shrinkable tubes are generally about 3-5mm.

　　The above are the standards and technical requirements of heat shrinkable tubes explained by military heat shrinkable tube manufacturers . I hope it can help everyone, thank you for watching, and see you next time.
