What You Have to Know about Heat Shrinkable Tube

Heat shrinkable tube can be used to protect wires and cables, but only by choosing the right heat shrinkable tube can you maximize the protection of your wires and circuits. In this article, let's explore the common parameters of heat shrinkable tube.

1、Inside diameter

The cross-section of a tube is cylindrical , and the inside diameter, usually denoted by the letter Φ, is the distance between the two ends of the tube. The unit of measure is millimeter.

2.Wall thickness

Wall thickness refers to the thickness of heat shrinkable tube. We know that heat shrinkable tube plays a role in insulation and protection, so the thickness affects the level of the insulation and protection. Similar to adding clothes when it's cold, thicker clothes are effective in keeping out the cold, and thinner clothes have relatively weak ability to keep out the cold. Therefore, the thicker the heat shrinkable tube, the better its mechanical protection.

3.Shrinkage rate

Heat shrinkable tube shrinks when heated, so the shrinkage rate is sometimes called the heat shrinkable rate. That is, the ratio of the inner diameter of heat shrinkable tube before shrinkage to the inner diameter after shrinkage. If the diameter of a heat shrinkable tube is Φ6 at room temperature and Φ3 after shrinkage, then its shrinkage rate is 2:1. Shrinkage rate reflects the degree of shrinkage capacity of heat shrinkable tube. The higher the shrinkage rate, the finer the heat shrinkable tube will be when fully contracted. Common shrinkage rates for heat shrinkable tube are 2:1, 3:1 and 4:1.

The wall thickness of heat shrinkable tube increases after shrinkage. So when we pick heat shrinkable tube, the more important wall thickness is the wall thickness after shrinkage, because after shrinkage is the real working condition of heat shrinkable tube.

4. Operating temperature

Operating temperature refers to the temperature at which the heat shrinkable tube can work normally and continuously. For example, the normal operating temperature of heat shrinkable tube is -55°C to 125°C. Exceeding this temperature does not necessarily guarantee longevity and normal operation.

5.Color

The most common colors of heat shrinkable tube are red, green, yellow, blue and black.
