Wrapping tape on a high voltage cable can be time consuming and error prone since the careful build-up of tape requires accurate half-lapping and constant tension in order to reduce build-in air voids. Rubber tapes are designed to stretch−some up to 1000%. Elongating the tape this way drives to compression, and that results in the strong self-fusion that provides great insulation and moisture protection.
One of the key features of Flex Tape Black is its ability to create a strong, waterproof seal. This makes it ideal for repairing leaks and cracks in pipes, gutters, and other surfaces that are exposed to moisture. Whether you need to patch up a leaky roof or fix a broken hose, Flex Tape Black can provide a long-lasting and durable solution.
Butyl seal tape is much easier to work with than the traditional sealants used for windows, so many people prefer to use it. It is incredibly supple and easy to bend and manipulate to the shape of the surface you’re using it on, making it ideal for installation on oddly-shaped windows and window frames.
In a typical tape splice, you’ll tug and pull out the tape, stretching it to just before the breaking point. The tape’s width narrows to about 1/3rd of its original size. The tape’s length increases; your hand travels very quickly up to 20” away from where you started. Quite often you’ll be wrapping in a tight location making this even more difficult. Proper taping techniques are critical to realizing the many performance benefits of rubber tape.
