Heat shrink tubing, also known as heat shrink, or heat shrink sleeves, is a type of thermoplastic tube that shrinks in diameter when heat is applied. It is commonly used in electrical and electronic applications to insulate, protect, and organize wires, cables, and other components.
The tubing is typically made from materials like polyolefin, fluoropolymer, or elastomer. It comes in various sizes, colors, and shrink ratios, which refer to the degree of contraction when heated.
Application: The tubing is placed over the component (such as a wire or cable) that needs to be protected or insulated.
Heating: When heat is applied, usually using a heat gun, oven, or similar heat source, the tubing begins to shrink in diameter. This process is reversible, so if the tubing isn't heated to the point of melting, it can be reheated and expanded again.
Contraction: As it shrinks, the tubing conforms tightly to the shape of the underlying component, creating a snug and protective covering.
Insulation: It provides electrical insulation, protecting wires and cables from environmental factors like moisture, dust, and chemicals.
Strain Relief: It can act as a strain relief, preventing wires from bending or breaking at stress points.
Color Coding: Different colors of heat shrink tubing can be used to distinguish between different wires or components.
Mechanical Protection: It offers physical protection against abrasion, vibration, and other forms of mechanical damage.
Sealing and Waterproofing: It can be used to create a watertight seal around connections.
Heat shrink tubing is widely used in industries like electronics, automotive, aerospace, and telecommunications. For more information about heat shrink tubing, check out our Heat Shrink vs Cold Shrink Tubing guide over at our Knowledge Centre.
