To use the tape, simply stretch it around the material you are trying to repair. As you wrap the tape in a circular motion, it begins to seal and “fuse” itself to the material. The most common forms of self-fusing / self-amalgamating tapes are made of silicone rubber (though other types also exist). They are designed to create a strong, seamless, rubbery, waterproof, and electrically insulating layer.
