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.
Another great feature of Flex Tape Black is its ease of use. The tape comes with a built-in cutter, making it easy to cut the tape to the desired length without the need for any additional tools. Simply peel off the backing, apply the tape to the surface you want to seal, and press it down firmly to create a secure bond.

This characteristic makes it ideal for both indoor and outdoor uses.

Self-bonding rubber tape, often referred to merely as rubber tape, is an innovative solution that has transformed the way we think about sealing, insulating, and repairing various materials. This unique type of tape is characterized by its ability to bond to itself without the need for adhesives, making it an invaluable tool in numerous applications, from electrical work to plumbing and beyond.
