The use of heat shrink tube industry
Heat shrink tubing is widely used in wiring waterproof of electronic equipment, sealing and fixing of wire branches, anti-corrosion protection of metal pipes and lines, as well as preventing loosening and falling off produced by polymer chain relaxation, such as underwater lighting, automobile fuel line, advanced wire harness, etc. Starting shrinkage temperature: 70℃; minimum complete shrinkage temperature: 125℃, low voltage standard color is green, yellow, white, black, blue, red, high voltage is red, yellow, green

High-voltage heat shrink tube and low-voltage heat shrink tube to distinguish between the selection of.
According to the different voltage is divided into low-voltage heat shrinkable tube, 10KV, 35KV is usually referred to as bus bar heat shrinkable sleeve (high-voltage heat shrinkable tube, high-voltage bus bar), etc.. Also known as heat-shrinkable tube, heat-shrinkable tube and so on, heat-shrinkable tube is a kind of insulation tube with high-temperature shrinkage, soft flame retardant, insulation and corrosion protection function, heat-shrinkable tube is composed of radiation multi-linked polymer, it is heated after the contraction of tightly wrapped cable joints, so as to achieve the purpose of insulation, sealing and protection.

Precautions for the use of heat shrink tube
1, heat shrinkable tube and heating equipment should not be too close, must pay attention to the distance between the fire and heat shrinkable tube, that is, 4 ~ 5cm evenly moving, in the heating shrinkage, do not exceed the upper limit of heat shrinkable tube temperature, for heat shrinkable tube, the temperature exceeds the upper limit of temperature resistance, will make our products "melt" phenomenon, will return to the initial state.

2, choose the right heating tool, heating and baking when the flame of the outer flame and the surface of the heat shrink tube at an angle of 45 degrees, must pay attention to move back and forth so that the overall heat shrink tube, slowly from one end to the other, heating to avoid bubbles, to ensure that the shape of the heat shrink tube shrinkage, to be trimmed after cooling.

3, heat shrinkable tube has different heat shrinkage ratio, heat shrinkable tube specifications generally refers to the product of the maximum inner diameter allowed after shrinkage of the casing and the shrinkage ratio multiplied. If the shrinkage ratio of the heat shrink tube is 2:1, that is, you can choose to use the heat shrink tube twice as large as the diameter of their products. For example, the diameter of the object is 20mm, we can choose the maximum diameter of 40mm heat shrinkable tube to use.

4, for linear objects such as wire, choose the product outside diameter of the size of the heat shrinkable tube specifications can be; power stations, electrical cabinets and other bus bar protection need to choose bus bar heat shrinkable tube; sealing requirements for the use of waterproof heat shrinkable tube.
