Sunbow double-wall heat shrinkable tube has excellent waterproof performance, so that the wiring harness no longer seeps and leaks, which completely solves the troubles of a wiring harness manufacturer. The wiring harness manufacturers are amazed that the double-wall heat shrinkable tube has a good waterproof effect, and Sunbow's manufacturing is the best. Since the cooperation, we have been placing orders in Sunbow, and there has not been a single quality problem.

With the development of the market, the quality of the products produced varies, and most of them are low-end products. The quality of the product cannot be guaranteed. In order to tempt the hearts of customers with low prices, many manufacturers also mean that some manufacturers will start to opportunistically. Use inferior hot melt adhesive for processing, and sell low-quality, substandard double-wall pipes to customers. The service life of the double-walled heat shrinkable tube is greatly shortened, which greatly damages the customer's products and causes serious quality accidents to the customer. ( PVC tube)

Wire harness customers have extremely strict requirements on the performance and appearance of heat shrinkable tubes: outer insulation, anti-corrosion, wear-resistant, flame-retardant, and highly waterproof. After many samples, these requirements could not be truly achieved. When we found Sunbow, we were in a state of doubt, and customers did not trust the heat shrinkable double-walled tube. Our company assures customers that Sunbow heat shrinkable double-walled tube adopts a certain brand of hot melt adhesive, and the water return effect is excellent, and it will never leak. The problem of water leakage is mainly the quality and proportion of the adhesive layer. The thickness standard of the double-walled tube is 3 times that of the ordinary heat shrinkable tube, while that of Sunbow is 3.5 times. At the same time, the UL certification of the product, RoHS, REACH environmental protection test report, customer Throwing doubts reluctantly sample. ( silicone tube)
