Almost all people know that heat shrink tubing, but few people know about it in details. Heat shrink tubing is available in a variety of colours to allow easier colour coding of wires and connections. Recently heat shrink tubing has been used more in PC modding to tidy up the interior of computers and provide a more aesthetic finish. As a reaction to this new market opening up, heat shrink tubing suppliers have started producing heat shrink tubing in luminous and UV reactive varieties. Although most heat shrink is used to provide insulation, heat shrink tubing is also available with a conductive lining to avoid the requirement to solder a joint before covering it. This may be considered poor engineering practice. Similar to heat shrink tubing is heat shrink end caps. Shaped like small mugs, these may be used to insulate cut ends of wires or cables. Heat Shrink Tubing was invented by Raychem Corporation. Leading global producers include Tyco (which owns Raychem), 3M, and Sumitomo Electric Industries (through Sumitomo Fine Polymer).

For this reason, 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 of components and parts used in thousands of applications.
