The special double wall heat shrinkable tube for automobile not only has excellent anticorrosion performance, but also provides protection for the friction parts of the parts. It is especially suitable for the compact small automobile harness, which is widely used in the current automobile industry. In particular, the double wall heat shrinkable pipe is installed on the automobile chassis, which can effectively prevent the corrosion of the brake oil pipe caused by muddy water and sand.
Double wall heat shrinkable pipe for automobile plays such an important role, so the quality of double wall heat shrinkable pipe is particularly important. A car manufacturer once asked our company about the common problems of special heat shrinkable tubes for cars. Previously, this car manufacturer purchased a batch of special double wall tubes for cars in an insulating sleeve business. When using, it found that air was often sealed in the heat shrinkable tubes, which made the heat shrinkable tubes have pimples on the surface. In order to eliminate such bubbles, it is necessary to use steel under the softening state of the heat shrinkable tubes The needle pierces the eye and deflates, but such behavior will cause many needle holes and cavities on the surface of the shrink finished heat shrink tube. Don't underestimate these seemingly small holes, so the double wall pipe in this state can't completely protect the oil pipe!
