164/328/560/580pcs boxed heat shrink tubing 2:1 electronic DIY kit wire connection tool accessories data line protection cable
Features
-
It has the functions of high-temperature shrinkage, soft flame retardant, insulation, and anticorrosion. It is widely used for insulation protection of wiring harness, solder joints and inductors, and anti-rust and corrosion protection of metal pipes and rods. The voltage level is 600V.
-
As the temperature goes from low to high, the polymer material will experience a glassy state of high elasticity. The performance of the glass state is close to that of plastic, and the performance of the highly elastic state is close to that of rubber.
-
The material used for the heat-shrinkable tube is glassy at room temperature and becomes a highly elastic state after heating.
-
In the production process, the heat-shrinkable tube is heated to a high elastic state, and then a load is applied to the heat-shrinkable tube to expand it. Under the condition of maintaining the expansion, the heat-shrinkable tube is rapidly cooled to enter the glass state, and the state is fixed. When in use, it will return to a highly elastic state after heating, but when the load disappears, it will retract.
