Despite its many benefits, Flex Tape is not without its limitations. While it can be used to fix a wide range of issues, it is not a permanent solution and may need to be replaced periodically. It is also not recommended for use on flexible materials or surfaces that constantly move or bend, as it may not adhere properly.
Rubber tape usually does not have an adhesive side but sticks to itself. This means it has to be stretched entirely around a cable to effectively adhere to itself using elastic tension against the backing.
In production plants and manufacturing facilities where steam, dripping water and elevated humidity are present, self-fusing rubber tapes provide much needed moisture protection.
