Advantages of Heat Shrink Tubing
Heat shrink tubing is one of the most effective tools you can have for organizing and protecting electrical cables. It is manufactured from cross-linked polyolefin material and is widely used in military, industrial, and commercial settings.
By fitting heat shrink tubing around your electrical cables and then heating the tubed area with a hot air gun, the tubing shrinks to fit your cables — protecting them from environmental hazards like moisture and shock while making them easier to identify.
Sizes are denoted as a ratio of expanded size. A 3:1 ratio means the tubing shrinks to 1/3 of its original diameter; a 2:1 ratio means it shrinks to half. Always select tubing that will shrink to a slightly smaller size than the cable being applied to.
Provided in the expanded state, heat shrinkable tubing "shrink wraps" intricate and irregular shapes with a simple application of heat. The result is a protective covering that greatly extends life, increases reliability, and improves performance.
