Information
With the wide application of double-walled heat-shrinkable tubes, today I will tell you about the application of double-walled heat-shrinkable tubes in automobiles.
 
Automobiles need to use double-walled heat-shrinkable tubes to seal and protect automobile wiring harnesses. Semi-rigid double-walled tubes for automobile wiring harnesses and double-walled heat-shrinkable tubes for automobile fuel pipes are specially designed for sealing and protecting automobile wiring harness pipes. The advantages of the semi-hard double-walled heat-shrinkable tube for automotive wiring harness are: insulation, anti-corrosion, wear-resistant, low melting point in the inner layer, mechanical strain buffer of the waterproof seal box, etc. The advantage of the double-walled pipe for automobile oil pipe is that it can effectively prevent damage caused by vibration, friction and corrosion, and improve the reliability of the pipeline. This double-walled heat-shrinkable tube is divided into inner and outer layers. The outer layer is a mixture of low-density high-pressure polyethylene and ethylene vinyl acetate copolymer (EVA). The inner layer is a very thin hot-melt sealing resin with strong adhesiveness. . When the double-walled heat-shrinkable tube is placed on the surface of the oil pipe with a diameter larger than the diameter of the oil pipe, and then heated after positioning, the double-walled heat-shrinkable tube will shrink to a predetermined size. Through the inner layer of hot-melt adhesive, the heat-shrinkable tube and the oil pipe Closely connected together without any gap in the middle, this kind of oil pipe protection method can greatly improve the service life of automobile oil pipes.
 
The use of double-walled heat-shrinkable tubing in automobiles is a new material that is accompanied by the increase in the anti-corrosion requirements of automobile brake tubing. It entered the country in the early 1990s and has been widely used in recent years. Especially in the current small cars equipped with high-power engines and the increase in ABS and power steering, the layout of the brake oil pipes is becoming more and more complicated, often interfering between the oil pipes and the oil pipes and related parts, double-wall heat shrink The tubing provides reliable protection for the tubing.
