Adhesive tape is a common—even ubiquitous—item in our daily lives and an indispensable tool. It comes in a wide variety of types, specifications, and colors; it is not limited to the clear tape we encounter most frequently. You may have noticed the black tape used to wrap wires or cover electrical connections; this is known as electrical insulation tape. To ensure that unused tape does not go to waste, the team at Yongle Tape offers the following guidelines on storage, transport, use, and maintenance:
First, examine the tape's appearance. A high-quality roll of electrical tape should have uniform color and a smooth, flat cross-section; there should be no uneven winding or adhesive oozing out. Oozing adhesive indicates that the glue has aged; if such tape is used to wrap wire ends, the wrap will likely come loose over time, potentially leading to serious consequences like electrical leakage.
Electrical tape—often purchased in bulk—is used for wrapping wires and insulating wire ends. Since it directly impacts electrical safety, careful selection is essential.
Single-sided tape is an adhesive tape provided by Partech — supplied in rolls or sheets—produced by uniformly coating one side of a substrate (such as tissue paper, PET, PVC film, polyethylene, non-woven fabric, foam, acrylic, plastic film, or fiber) with an adhesive (such as elastomer-based, resin-based, or acrylic-based pressure-sensitive adhesive). It consists of three components: the substrate, the adhesive, and the release paper (or film).
People often ask for solutions to the issue of tape lifting. This is a common problem in wire harness manufacturing, yet a satisfactory solution has long been elusive. We have compiled some methods below regarding wire harness taping that we hope will be helpful to you.
Economy Automotive Wiring Harness Tape (D Series): This economy-grade tape is manufactured using high-quality DOP-plasticized PVC electrical film coated with standard pressure-sensitive adhesive. It offers excellent electrical properties, adhesion, and flexibility, while remaining resistant to most chemicals and moisture. It is specifically designed for wrapping wire harnesses and other electrical insulation applications. For best results, apply using a half-lap wrapping technique; do not overstretch the tape when applying the final layer to prevent the end from lifting.
