Application of HUS Adhesive Double - wall Heat Shrinkable Tube in Automobile Industry

Car market need to use HUS plastic double-walled heat pipe to seal the car harness protection, Kewei heat shrinkable car harness dedicated semi-hard double-walled tube and automotive tubing dedicated plastic double-walled heat pipe are specifically for the car Wiring harness pipes and other sealing protection. Automotive wiring harness dedicated semi-hard double-walled tube advantages are: insulation, corrosion, wear, the inner layer with low melting point, waterproof sealing box mechanical strain buffer. Automotive tubing dedicated double-walled tube has the advantage of being able to effectively prevent the vibration, friction, corrosion caused by damage, improve the reliability of the pipeline. This kind of plastic double-walled heat-shrinkable tube is divided into two layers inside and outside, the outer layer is low-density high-pressure polyethylene and ethylene vinyl acetate copolymer (EVA) mixture, the inner layer is very thin adhesive hot type Sealing resin. When the plastic double-walled heat-shrinkable tube is larger than the diameter of the tubing into the tubing surface, positioning and then heated, the plastic double-walled heat shrink tubing will shrink to a predetermined size, through the inner hot melt adhesive, the heat Shrinkage and tubing tightly connected together, the middle without any gaps, this tubing protection method, can greatly improve the life of the car tubing. The use of plastic double-walled heat-shrinkable tube is accompanied by the improvement of anti-corrosion requirements of automobile brake tubing. In the early 1990s, it has entered our country and has been widely used in recent years. Especially in the current small car to install high-power engine and ABS and help increase the power, is the brake tubing layout more and more complex, often between the tubing and tubing and related parts of the interference between the problem, The heat pipe provides a reliable protection for the tubing.
