Heat shrink tubing ,originally developed in the 1950s, is a type of plastic tubing that shrinks in diameter when heated.

It is used widely in electrical applications, protecting cables from a variety of degrading elements including chemicals, weather and general abrasion. It’s also very useful for bundling and color coding your cabling as it comes in a wide range of colors and can even be printed with labels, to help with identification.

When you apply the Elastomeric Heat Shrink Tubing to connectors, it helps relieve the stress of cumulative wear and tear caused by the actual movement and bending of the cabling. If the cables endure some serious flexing in their use, they may need firmer protection and semi-rigid heat shrink tubing would be preferable here.

Not only can heat shrink tubing provide additional strain relief, but it can also provide extra insulation. Heat shrink tubing has great electrical qualities which makes it ideal for use with connections, terminations, and circuit board applications requiring additional environmental and electrical protection.

Heat Shrinkable Fiber Optic Splice Protector also provides an extra layer of protection for the cable by working as a sealer. It can be placed over substrates, connections, joints, and gaps to protect them from moisture, chemicals, and dust. Tubing defends against environmental hazards by providing UV, oxidation, corrosion, and abrasion resistance as well.

Although heat shrink tubing can be utilized in many preventative maintenance applications, it can also be extremely helpful when making Expandable Braided Sleeving repairs. Whether the fixes are temporary or permanent, heat shrink tubing can be used to cover damaged cable jackets, insulation, connections, or cable splices. It makes for a quick and easy fix while you wait for the cable to be replaced, but it also works effectively enough to serve as a permanent repair in some cases.
