Performance: With high temperature shrinkage, soft flame retardant, insulation and corrosion prevention function. Widely used in a variety of wiring harness, solder joints, inductance insulation protection, metal pipe, rod rust, corrosion prevention. Voltage level: 600V.
As the temperature goes from low to high, the polymer material experiences glassy state -- high elastic state. The performance of glassy state is close to that of plastic, and the performance of high elastic state is close to that of rubber.
The material used in the heat shrinkable tube is glass at room temperature and becomes high elastic when heated.
Use: During production, heat shrinkable tube is heated to the high elastic state, and the load is applied to make it expand. Under the condition of maintaining expansion, the tube is cooled rapidly, so that it enters the glass state, and this state is fixed. As soon as it is heated in use, it will change back to a high elastic state, but then the load is gone, it will shrink back.
