The importance of high temperature resistance
Cloth tape is abbreviated as PET tape. Commonly used cloth tape has the following types: fiber cloth tape, polyester cloth tape, wool polyester cloth tape, flannel tape, felt tape, electrical insulation waterproof tape, non-adhesive cloth tape,The color of commonly used cloth tape is black. The Car Audio & Video Wiring Harnesses tape used in automotive wiring harnesses has characteristics such as temperature resistance, flame retardancy, noise reduction, compatibility of wire insulation, abrasion resistance, low fogging, oil stain resistance, and corrosion resistance are very important. For the wiring harness in the engine compartment, the ambient temperature in the engine compartment is the highest. In some specific locations, such as above the engine block, the maximum storage temperature can reach 135℃, and the maximum storage temperature under the hood can also reach 95℃, so The place closest to the engine requires high temperature resistance of the tape. The tape used on the engine wiring harness generally has two functions: the wiring harness does not have a protective sleeve, and the tape plays the main protective role. At this time, the high temperature resistance of the tape must reach 130°C. The wire harness has a protective sleeve, and the tape mainly plays the role of fixing the protective sleeve. At this time, the high temperature resistance of the tape must be above 105°C. Indoor wiring harnesses, such as instrument panel wiring harnesses, indoor floor wiring harnesses, ceiling wiring harnesses, and four-door wiring harnesses. These wiring harnesses are inside the machine room. The tape used in the wiring harnesses can meet the requirements when the high temperature resistance reaches 85°C.
