Heat shrink tubing is an inexpensive way to protect cables from any environmental factors that could damage or interfere with cable operation. Heat shrink tubing not only cushions wear, liquids, and temperature/humidity changes, but is also a cost-effective method of cable organization and color-coded identification. This article will further explore the benefits of heat shrink tubing to better understand how it improves cable reliability and maintenance, and its value in cable routing and construction.

First, size and color customization

Depending on the supplier and manufacturer, heat-shrink tubing is measured in millimeters or inches and is based on the pre-shrink diameter of the tubing. Once heated (e.g. 90 degrees Celsius), the tube will become half its original size. This ratio means that once heat is applied, a 2-inch pre-shrink diameter will shrink to 1 inch diameter.

Each diameter is available in a variety of colors, and by cutting colored heat shrink tubing at both ends of the cable route, it's easy to add some tissue color coding to the installation. Heat shrink tubing is also a great way to bundle cables together, and this color coding helps increase the recognition of the grouping.

Second, how to protect the cable?

Heat shrink tubing is a fast and effective way to protect cable terminations from environmental risks to cables. With a temperature range of -55 degrees Celsius to 125 degrees Celsius, shrinkage is flame retardant and the perfect low-cost way to protect cable ends and terminations.

As a protective covering, heat shrink tubing is also effective in applications where wear and abrasions may occur in low-impact environments. Whether plugging and unplugging cables, or cables or connections outdoors or in environments that are susceptible to interference from people or other devices. It also provides a good barrier to unwanted moisture, residues, and even chemicals in sensitive cable connections.
