You should use a minimum of two half-lapped layers of vinyl tape to insulate and jacket low-voltage components. A half-lap (see Figure above) consists of overlaying each turn by one-half the width of the tape. The general rule of thumb calls for a tape thickness of 1.5 times the thickness of existing wire or cable insulation. In every case, tension on the tape should be sufficient to conform the tape evenly to the surface. A slight reduction in tension is encouraged for the final wrap. Trim the tape end and allow it to return to shape before pressing down with the thumb to avoid lifting or flagging.

5. Easy Application Applying self-fusing rubber tape is straightforward. It can be easily wrapped around wires or surfaces without requiring special tools or adhesives. Once layered, the tape fuses to itself, providing a snug fit that ensures effective insulation and protection.

Additionally, butyl rubber is a preferred material for environmentally conscious companies. Its production process typically has a lower environmental impact compared to natural rubber, as it does not rely on extensive agricultural practices. Furthermore, the durability and longevity of butyl rubber rolls contribute to sustainability, reducing waste over time.
