Polyvinyl chloride tape, that is, PVC tape is the most commonly used in the protection of wiring harness joints. Blue PVC tape and black PVC tape are relatively common PVC insulating tapes. 20m in length, 40mm in width, and 0.2mm in thickness are common specifications for blue PVC insulating tape, while commonly used black PVC insulating tape is 20m in length, 0.2mm in thickness, and 38mm in width. Since the automobile design and vehicle safety performance of most domestic manufacturers are gradually in line with international standards, wiring harness manufacturers have reduced the use of PVC insulating tape for automobile wiring harness contacts.
Before using the blue polyvinyl chloride insulating tape, it is necessary to fix the tape near the wrapping machine, put the tape head into the cutter slot, connect the power supply and press the contact point in the wrapping machine for wrapping treatment. The raw material price of the blue polyvinyl chloride insulating tape is relatively low, and the machine wrapping method improves the convenience and efficiency of the wrapping work. However, the blue PVC tape has many layers, poor overall aesthetics, takes a long time, and is difficult to waterproof. The difference between black PVC insulating tape and blue PVC tape is mainly reflected in the thickness and glue content of the tape, and its use method is basically the same as that of blue PVC insulating tape.
