What is a heat-shrinkable tube, a heat-shrinkable tube is a special material of plastic, which can shrink quickly at high temperatures. When we connect two wires. Put the heat shrink tube on the metal connection. Then use a heat gun to bake the heat shrink tube. It will shrink quickly and wrap around the metal joints, so that we don’t need to use tape to wrap it. Improve work efficiency, and the safety and reliability of the connection.
