The Versatility of Black Flex Tape
In summary, self-bonding rubber tape is a remarkable tool that combines simplicity with functionality. Its unique properties allow it to be used in a wide range of situations, making it a favorite among professionals and DIYers alike. Whether used in electrical work, plumbing repairs, automotive maintenance, or creative projects, this tape consistently delivers reliable performance and ensures durability in even the most challenging environments. As awareness of its versatility grows, self-bonding rubber tape is likely to continue being a go-to solution in various industries and among individuals seeking practical, easy-to-use repair solutions.
(4) Inherent flame retardant, which has no conductivity when the combustor forms ash;
Look closely at this tape and you'll see it has a tapered design. This is so that when it is applied with 50% overwrap (the green centreline helps with this) you end up with a smooth finish and less overall bulk.

Fire-resistant electrical tape is versatile and can be used in numerous applications. In industrial environments, where heavy machinery and high electrical loads are common, the risk of electrical fires increases. Using fire-resistant tape to insulate wires and connections can substantially mitigate this risk. It is particularly beneficial in high-temperature applications, such as motors, transformers, and circuit boards.
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.
