Heat shrink tubing is a type of tubing that shrinks in diameter when heat is applied, providing a protective covering for wires, cables, and other components. It is typically made from materials such as polyolefin, fluoropolymer, or PVC, and is commonly used in electronics, automotive, and aerospace industries, as well as for various DIY projects.
Heat shrink tubing comes in various sizes, colors, and shrink ratios. The shrink ratio indicates how much the tubing will shrink in diameter when heated. For example, a 2:1 shrink ratio means the tubing will shrink to half its original diameter.
