Introduction        
The cross-linked polyolefin heat-shrinkable tube has a zigzag-like unevenness on the inner wall in the radial direction, which acts as an air guide to avoid bulging and wrinkles caused by holding the heat when the heat-shrinkable tube shrinks on the curved rubber hose. By covering the outer surface of the automobile rubber water pipe with heat shrinkable tubing, it can effectively avoid the friction between the automobile rubber water pipe and other parts of the automobile. At the same time, it can also prevent the automobile rubber water pipe from colliding with the stones and gravel on the road surface to cause abrasion, so as to protect the automobile pipeline. To extend its service life.
