Heat shrink is an optimal go-to for cable management. Here are six questions that we are commonly asked that will hopefully help you tackle your next project with ease!

1. Why should I use heat shrink?
Heat shrink is designed to provide beneficial cable management, such as repairing, relieving strain, bundling/organizing, sealing, and protecting. The bottom line is that heat shrink material creates a durable watertight seal around electrical wires/connectors. It provides optimal protection against harsh environmental conditions, moisture, and abrasion.

2. If I have electrical tape, can I use that instead for cable management?
The issue with electrical tape comes down to durability as it is more susceptible (than heat shrink is) to abrasion and everyday wear and tear. Once you use heat shrink (which is designed for a perfect fit) on a cable, the heat shrink and cable then become a unified item that withstands years of use.

3. What temperature is required for heat shrink to shrink?
Heat shrink that is manufactured from specially formulated polyolefin cross-linked compounds has a fast shrinkage upon application of heat above 120°C.

4. What temperature range does heat shrink withstand?
Heat shrink has a continuous operating temperature range from -55°C to 135°C.

5. Is it easy to install heat shrink?
Yes, the process is pretty simple as all that is required is the heat shrink material, the object that you are wanting to seal, and a heat source (such as a heat-gun or hair dryer). Heat shrink tubing comes in a variety of sizes and colors.

6. How can I prevent my heat shrink tubing from splitting?
It’s a good practice that you allow the tubing to recover at least 20% to avoid any type of splitting. Here are some other quick tips of the trade for optimal installation:
– Ensure that the heat-gun remains at the recommended temperature for proper shrinkage
– To achieve even heat dispersion, use a reflector on the heat-gun (as not distributing the heat properly is a key factor of why tubing splits).
