The PVC is a very common material in the market at present. The main component is Polyvinyl chloride. It is a polymer polymerized by vinyl chloride monomer (VCM) with peroxide, azo compound and other initiators or by free radical polymerization mechanism under the action of light and heat.The wire harness is fixed on the whole vehicle body, and the damage of the harness directly affects the performance of the automobile circuit. Therefore, the external protection of the harness plays a vital role. Reasonable external protection materials and binding methods can not only ensure the quality of the harness, but also reduce the cost and improve the economic benefit. We use PVC tubing to protect the wire harness because it has excellent performance: ✔ PVC Tubing has a relatively low price. ✔ PVC Tubing has a good appearance. The inner and outer walls of the tube are smooth, and the color is uniform. ✔ PVC Tubing is soft and elastic, so it is mainly used at the branch of harness bend elbow to make the conductor transition smoothly. ✔ PVC Tubing has good physical properties: certain heat resistance, ductility, and toughness. ✔ PVC Tubing has excellent electrical properties, acid, and corrosion resistance. ✔ PVC Tubing has high flame retardant performance, our PVC tubing meeting the flame retardant grade certified by UL 224, VW-1 and JQA F-mark. ✔ PVC Tubing has different temperature resistance grades，We can provide grades A and B，The heat-resistant temperature of B is 70 ℃, and A is 125 ℃. ✔ PVC Tubing has wide range of applications: in addition to automobiles, it can also be used in electronic components, household appliances, machinery, toys, and sporting goods.
