Heat shrink tubing is a special polyolefin material heat shrinkable sleeve.

Performance: with low temperature shrinkage, soft flame retardant, insulation corrosion protection function. Widely used in a variety of wiring harness, solder joints, inductors, insulation protection, metal pipe, rod rust, corrosion and so on. Voltage level 600V.

Polymer materials with the temperature from low to high to go through the glass state - high elasticity, glassy state close to the performance of plastic, high elastic properties close to the rubber.

The material used for the heat-shrinkable tube is glassy at room temperature and becomes a high elastic state after heating.

Use: the production of heat shrink tubing heated to high elasticity, the application of the load to expand, in the case of maintaining the expansion of the rapid cooling, so that it into the glass state, this state is fixed. When used in a heating, it will change back to high elastic state, but then the load is not, it will retract.
