What is the purpose of tape wrapping for Automobile wiring harness?

The role of Automobile wiring harness tape is to bundle the wire, protect the wire, do insulation protection layer, sound absorption and noise reduction, marking and marking, fixing, etc., while playing the role of wear-resistant, flame retardant, anti-corrosion, prevent interference, reduce noise, beautify the appearance.

In the harness design and manufacturing process, tape has not received much attention, the choice of tape with blindness, the following classification of automotive wiring harness with the main characteristics of the tape, material, the choice of tape, the use of tape to analyze and explain.Electronic wiring harness

1. automobile wiring harness classification and main characteristics of commonly used tape according to the material and characteristics of commonly used tape is broadly divided into three categories: PVC tape; cloth-based tape; sponge tape.

2. PVC tape PVC tape is known as polyvinyl chloride electrical insulation pressure-sensitive adhesive tape, its substrate is a soft PVC film, adhesive for natural rubber, acrylic rubber, synthetic rubber, etc. as the main material of the adhesive layer, PVC tape has good temperature, cold, corrosion, oil and dirt resistance, flame retardant and other characteristics.Aviation wiring harness

PVC tape is available in black, white, blue, green, yellow, red, grey and transparent colours.

The standard thickness of PVC tape is 0.12mm, 0.15mm, 0.2mm and 0.25mm.

PVC tapes have different working temperature ranges due to different auxiliary ingredients. The commonly used PVC tapes have three ambient temperature ranges: -40 to 85°C; -40 to 105°C; -40 to 135°C (special).

3. Cloth-based tapes Cloth-based tapes are referred to as PET tapes. The following types of cloth-based tapes are commonly used: fibre cloth-based tapes; polyester cloth-based tapes; wool polyester cloth-based tapes; fleece tapes; felt tapes; electrical insulation and waterproof tapes; non-adhesive cloth-based tapes, etc.

The common colour of cloth-based tape is black, and the common specifications of cloth-based tape are generally 20 x 25, 40 x 25, etc. The thickness of the tape is generally 0.25~0.8mm.
