The classification of heat shrinkable tubes and the difference in the use of heat shrinkable tubes

Heat-shrinkable tube is a thermoplastic sleeve-shaped product. The low-pressure heat-shrinkable tube is called a thin tube in the industry. The high-pressure heat-shrinkable tube, such as 10kv heat-shrinkable tube and 35kv heat-shrinkable tube, we call it busbar heat-shrinkable tube or heat-shrinkable tube. It is simply called busbar; today, we will talk to you about the classification of heat shrinkable tubes. This chapter mainly talks about materials and colors.

Heat-shrinkable tubes can be divided into PE heat-shrinkable tubes, PET heat-shrinkable tubes, and radiation-crosslinked PE heat-shrinkable tubes according to their materials. It seems that there are quite a lot of materials to choose from for making heat shrinkable tubes, so the editor will choose one or two for you and give you detailed science.
First of all, let`s talk about PE, which is the most widely used material at present. PE is the abbreviation of the English word polyethylene, and the Chinese name is polyethylene. Similar to wax, it has better low temperature resistance and can resist most acids and alkalis (not resistant to acids with oxidizing properties). It is insoluble in common solvents at room temperature, has little water absorption, and has excellent electrical insulation. Because of its wear resistance and good insulation, it is widely used in the manufacture of heat shrinkable products. For example, single-wall heat-shrinkable tubes, double-wall heat-shrinkable tubes, and high-voltage busbar heat-shrinkable tubes are all made of polyethylene.
Finally, I would like to introduce PET, the material of the heat-shrinkable tube. PET is the best material to replace PVC. This material is extremely environmentally friendly, and its environmental performance far exceeds the latest EU RoHS2.0 directive. It is an ideal insulation coating material. The Chinese name is polyester, and PET is a white powder without a specific shape and structure. Sensitive to light and heat. In the case of high temperature and prolonged sunlight exposure, it will decompose and produce chlorides. There are many colors to choose from. And the color is brighter and nicer.
We all know that heat-shrinkable tubes can be divided into 1kv heat-shrinkable tubes, 10kv heat-shrinkable tubes, and 35kv heat-shrinkable tubes according to the voltage level. The color of the 1kv Heat Shrinkable Tube is conventionally available in seven colors: red, blue, yellow, green, black, white, and two-color. In addition, we also have several special colors such as transparent, purple, brown, gray, orange, and transparent. It is also a manufacturer of fiberglass tubes, with two materials: silicone fiberglass tubes and silicone rubber fiberglass tubes.
