Heat shrinkable tube, also called heat shrinkable protective tube, is to provide insulation protection for wires, cables and wire terminals. The main material is plastic, which is a special polyolefin material. The outer layer is made of high-quality soft cross-linked polyolefin material and The inner layer is made of composite hot-melt adhesive. The outer layer has the characteristics of insulation, corrosion resistance and wear resistance. The inner layer has the advantages of low melting point, waterproof and sealing, and high adhesion.
Heat-shrinkable tube has the characteristics of soft flame-retardant, high-temperature shrinkage, insulation and corrosion resistance, and is generally used for packaging and insulation of electronics, electrical appliances and batteries.
In production operations, it is generally compressed by using a hair dryer, hot air blower or heat shrinking machine to play a role in protection and insulation.
Heat shrinkable tube can be divided into pvc heat shrinkable tubing, 35KV high voltage busbar protection heat shrinkable tube, pet heat shrinkable tube, rubber double-walled heat shrinkable tube, radiation crosslinked PE heat shrinkable tube according to material , 10KV high-voltage busbar protection heat shrinkable tube, imitation wood grain heat shrinkable tube.
