Self-fusing silicone electrical tape is a type of insulating tape made from high-quality silicone rubber. Unlike traditional electrical tape, which relies on adhesive for bonding, self-fusing silicone tape adheres to itself when stretched and pressed together. This unique feature allows it to form a strong, weather-resistant bond without the mess of adhesives. The tape is typically available in various colors and thicknesses, catering to different needs and preferences.
