The definition of the heat shrinkable tube

2022-02-12
Performance of heat shrinkable tube: it has the functions of high temperature shrinkage, soft flame retardant, insulation and anti-corrosion. It is widely used in the insulation protection of various wire harnesses, solder joints and inductors, and the rust and corrosion prevention of metal pipes and rods. Voltage class: 600V.

Polymer materials will experience glass state high elastic state with the temperature from low to high. The performance of glass state is close to that of plastic and that of high elastic state is close to that of rubber.

The material used in the heat shrinkable tube is glassy at room temperature and becomes highly elastic after heating.

Use of the heat shrinkable tube: during production, heat the heat shrinkable tube to a high elastic state, apply a load to expand it, and quickly cool it under the condition of maintaining expansion to make it enter the glass state. This state is fixed. When in use, once heated, it will return to the high elastic state, but when the load is gone, it will retract.
