The quality of Sunbow PVC casing is in the top three, and Huawei has no quality complaints in five years.

  Many international brands such as Samsung, Siemens, Philips, Haier, Midea, Gree, Huawei, etc. all choose Sunbow's PVC sleeve, and many domestic peers envy Sunbow. Just received good news from Huawei customers, Sunbow has successfully entered Huawei's supplier system, and Sunbow's PVC sleeves can be printed with Sunbow's trademark and UL number, which means that Sunbow will have the opportunity to supply PVC sleeves for more and more wire suppliers under Huawei.

At present, there are many manufacturers producing PVC sleeves in China, with mixed quality, chaotic price and no standard. Most of the peers do not include transparent color, and the phthalates are not up to standard, and the size only covers 1.0-12.0mm.

  Huawei chose Sunbow's PVC bushing, which has a temperature resistance of 105 degrees and a flame retardant grade of UL VW-1. We have cooperated with Huawei's wire suppliers for five years, and there has not been a quality complaint in these five years.
