Do you know the precautions for the use of PVC heat shrink tube For sale? Let’s take a look at it briefly below!
1. When cutting the heat-shrinkable tube, the incision should be neat and smooth, and no burrs or cracks should be produced, so as to avoid the stress concentration generated during heating and shrinking and spreading along the crack.
2. The heat-shrinkable tube and the heating device should not be too close, and attention must be paid to the distance between the fire and the heat-shrinkable tube, that is, 4~5cm to move evenly.
3. The heat shrinkable tube has an upper limit of temperature resistance. When heating, be careful not to exceed the upper limit of the temperature resistance of the heat shrinkable tube, and be careful not to focus on heating in one place, otherwise it will cause uneven thickness or burn the sleeve.

4. Select a suitable heating tool. When heating and baking, the outer flame of the flame forms an angle of 45 degrees with the surface of the heat shrinkable tube. Be sure to move back and forth to heat the heat shrinkable tube as a whole. It should be slowly moved from one end to the other end. Evenly, avoid air bubbles, ensure the shape of the heat shrinkable tube after shrinkage, and trim it after cooling.
5. Different use environments have different requirements for heat shrinkable tubes. For linear objects such as wires, you can choose the specifications of heat shrinkable tubes with the same outer diameter of the product; the protection of busbars such as power stations and electrical cabinets requires busbars Heat-shrinkable tube; choose waterproof heat-shrinkable tube if sealing is required.
The above is a brief introduction to the relevant knowledge about the precautions for the use of PVC heat shrink tube For sale.
