General Description
Shrinkage tubes, also known as heat shrink tubing or heat shrink sleeves, are a type of electrical insulation tubing that shrinks in size when exposed to heat. They are commonly used in various industries, including electronics, automotive, aerospace, and telecommunications.

Material of Heat Shrink Tube
Shrinkage tubes are typically made of a polymer material, such as polyolefin or polyvinyl chloride (PVC). The tubing is expanded or extruded to a larger diameter, allowing it to be easily placed over wires, cables, or other components that need insulation, protection, or bundling.
Shrink Theory, Shrink Method and Tube Function
When heat is applied to the shrinkage tube, it undergoes a process called “recovery” or “shrinking.” The heat can be applied using a heat gun, oven, or even an open flame (depending on the type of tubing and application). As the tubing heats up, it starts to shrink uniformly, conforming tightly around the objects it is covering. This creates a secure and insulating barrier that protects against moisture, dust, abrasion, and electrical shocks.
Shrinkage Ratio, Size and Color
Shrinkage tubes come in various sizes, colors, and shrink ratios. The shrink ratio indicates the degree to which the tubing will shrink down from its expanded size. Common shrink ratios include 2:1, 3:1, and 4:1. The choice of shrinkage tube depends on the application requirements, such as the diameter of the wires or cables being covered and the level of insulation and protection needed.
Overall, shrinkage tubes are widely used for electrical insulation, cable management, and bundling purposes due to their ease of use, versatility, and reliable protection properties.
