How does the heat shrinkable tube have the heat shrinkable function
The heat-shrinkable tube is a polymer material that undergoes a glass state-high elastic state as the temperature changes from low to high. The performance in the glass state is close to plastic, and the performance in the high elastic state is close to rubber. The material used for the heat-shrinkable tube is glassy at room temperature and becomes highly elastic after heating. So it has the function of heat shrink.

How does the heat shrinkable tube have the heat shrinkable function
During production, the heat shrinkable tube is heated to a high elastic state, and a load is applied to expand it, and it cools rapidly while maintaining the expansion, so that it enters the glass state, and this state is fixed. When heated in use, it will return to a high elastic state, but then the load is no longer, it will retract.

How does the heat shrinkable tube have the heat shrinkable function
Performance of heat-shrinkable tube: It has the functions of high-temperature shrinkage, soft flame retardancy, and insulation corrosion resistance. Widely used in the insulation protection of various wire harnesses, solder joints, inductors, rust and corrosion prevention of metal pipes and rods. The general withstand voltage is 600V, and the withstand voltages of 1KV, 10KV, and 35KV are busbar heat-shrinkable tubes, which are widely used for cable protection in outdoor substations.
