Polyolefin & PVC Heat Shrink Tubing

Heat shrink protection is an excellent technique for protecting crucial electrical connections and keeping wire connections secure. At Waytek, you’ll find every option of heat shrink tubing from PVC to extra heavy-duty polyolefin. We offer heat shrink products suitable for marine applications, and even products approved to all major automotive OEM splice sealing applications.

PVC and polyolefin heat shrink tubing can both be applied and shrunk in various conventional ways that are simple and easy enough where just about anyone can use them. Shrink temperatures are low enough that no special equipment other than basic heat guns or butane micro torches are needed. Both materials are highly resistant to common automotive, marine and aerospace fuels, as well as many household and electrician cleaning fluids and chemicals.

Polyolefin tubing is highly resistant to flame and abrasions, extremely flexible and has excellent chemical, physical and electrical properties. It also has a low shrink temperature that can be easily marked for identification purposes. Polyolefin heat shrink tubing meets UL, CSA and military specifications.

Like polyolefin, PVC is suitable for low to medium voltage applications. Typical applications for heat shrinkable tubing include: electrical insulation, circuit protection, cable bundling, color coding or identification, strain relief, mechanical protection, corrosion protection, abrasion protection and more.

What Is Heat Shrink Protection?

At its most basic, heat shrink protection, also called heat shrink tubing or heatshrink, is an insulation technique.

Before an automotive wire is connected, a sleeve is fitted over the wire. Once the wiring is complete, the sleeve is moved over the connection. The sleeve is then exposed to hot gas via an oven, a hot gas gun, or some other technique that applies heat, and it shrinks around the connection, providing tight insulation. It's generally made of nylon or polyolefin, such as propylene or similar polymers, as these materials shrink radially, not longitudinally. In other words, the diameter of the tube becomes smaller, but it won't get shorter as you heat it. You'll also be able to find it in a variety of colors, allowing you to maintain any color designations on wires as you need to make repairs.

What Are Some Uses Of Heat Shrink Protection?

The most common use of heat shrink is to secure wiring connections against abrasion and other damage and provide insulation where it can be difficult to use insulated wires otherwise. But it has a multitude of other uses around your fleet. In addition to strain relief, it can be used to replace worn insulation on wiring almost anywhere on a vehicle, bundle together multiple wires to keep them from hanging down or otherwise being too loose, protecting small parts from abrasion, or even creating cable entry seals for environmental protection.

What Are Some Considerations When Selecting Heat Shrink?

There are several considerations when choosing heat shrink. One is whether to select single wall vs. dual wall heat shrink. While single wall is far more common, dual wall, also known as adhesive lined tubing, provides a much stronger seal and connections, among other benefits.

Shrink ratio is another key consideration; heat shrink ratios compare the original heat shrink tubing in relation to its shrunken, final form. Ranging from 2:1-4:1 ratios, heat shrink will reduce to 50%-75% of its original size, respectively, once heat is applied.

In addition to these, it is also important to choose the right shrinkable tubing size. To do this, simply measure the diameters of the smallest and largest parts you will be covering with the tubing, then select heat shrinkable tubing that is twenty to thirty percent larger than your largest measurement.

What Heat Source Should I Use for Heat Shrink Tubing?

The best heat sources will be ones that offer consistent, dry heat, such as a hot gas gun, or by placing the wire and connection in an oven if possible. In a pinch, you can use other heat sources, such as a torch flame, but that should be done with extreme care and only if you have no other option for shrinking the tubing. Open flames and other focused heat sources have the potential to melt the tubing, unevenly shrink it, over shrink it, and cause other damage, some of which may not be obvious until the connection is put to heavy use.

How Can I Ensure A Good Seal?

First, strip away any worn insulation or other material from the wire. This will ensure the best possible seal. If you need to shift the sleeve over a connection and it's a tight fit, use only a silicon-based lubricant to move the sheath. Anything else may corrode the wire or damage the sleeve. Heat the sleeve consistently and with a broad-based heat source so that it shrinks evenly, and keep a careful eye on the shrinking so that you don't over shrink the material or otherwise damage it.

Heat shrink protection is a handy and simple technique that any member of your fleet can use to make quick and effective repairs. It's always a good idea to have some available, and you'll want to choose the absolute best.
