What Is Butyl Tape? Everything You Need To Know

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.

The main issue with buying tape online is that there are literally dozens of different types of adhesive tape on the market. Within each of these types, you can select from different options such as color, width, and thickness. The high degree of variation allows clients to select tapes that are perfectly tailored to their needs. However, some consumers can feel overwhelmed when reviewing their choices. Additionally, when you buy tape online, you have no way of knowing exactly how well the tape will work until your order arrives. Imagine buying a custom packing tape only to discover when it arrives that the width isn't compatible with your box sizes!
