There are several reasons why butyl sealant tape is chosen over other sealing materials:

Self-fusing rubber tape, also known as self-vulcanizing tape, is made from a specialized rubber material that adheres to itself when stretched and wrapped around an object. Unlike traditional tapes, which rely on adhesive to stick to surfaces, self-fusing tape bonds through a process called vulcanization. This means that when the tape is applied under tension, the molecules of the rubber intermingle and create a solid, impermeable layer that is both waterproof and electrically insulating.
