In addition to being built differently than other tapes, most electrical tapes used by professionals are UL Listed, which means that they have been vigorously tested for performance when exposed to environmental elements, such as cold temperature, moisture, and sunlight. UL Listed electrical tapes are also tested for physical properties, including backing strength, elongation, and adhesive strength and must meet a high standard in order to qualify for the listing. UL Listings exist for many other types of tape – such as foil and film HVAC tapes – but each listing revolves around the specific type of tape in question. So, while your foil tape may meet UL Listing requirements for sealing rigid ducts in HVAC applications, it would not meet the code if used in an electrical application.

Adhesives are a sadly overlooked aspect of tape selection. When you're purchasing tape for your business, it's easy to think about things like the material and the number of rolls. But too often, people don't consider the importance of the tape's adhesion. Different varieties of tape use different types of adhesive with different properties. If you don't factor in the adhesive type when you choose your tape, you might end up with an adhesive that's too weak or too strong for your projects. Too weak, and the tape will come loose. Too strong, and the tape might rip off paint or damage cardboard.
