Andy is the purchaser of an internationally renowned heavy truck wiring harness manufacturer in Russia. Although he has not been in the job for a long time, his purchases are very smooth. At the end of 2021, she purchased a batch of fiberglass sleeving from China to insulate and protect their various wiring harnesses. The original manufacturer's FIBERGLASS SLEEVING was smooth for the first month, but after 3 months, the problem came. The staff in the production workshop reported that the cold resistance level of the FIBERGLASS SLEEVING did not meet the standard, and cracks appeared when bending the wire harness. Andy was very distressed, and the boss asked him to solve the problem within 2 weeks at the earliest. ( PET braided sleeve)

Andy contacted the original FIBERGLASS SLEEVING manufacturer, and the other party replied that this FIBERGLASS SLEEVING is equipped with high-quality raw material glass fiber yarn and imported resin oil as standard, with a service life of at least 1 year. Let Andy check the temperature of the working environment. When he learned about the extremely cold scene of -50°C, the original FIBERGLASS SLEEVING manufacturer said that the FIBERGLASS SLEEVING can only be replaced once every 3 months, and there is no FIBERGLASS SLEEVING. can be replaced. Andy is very helpless. The working time of the wiring harness is generally at least 10 years. If the outer FIBERGLASS SLEEVING is not strong enough, it will be replaced every 3 months, which will be a huge loss and a loss-making business. （ PVC sleeve)

Andy could only find a new fiberglass sleeving supplier. A total of 10 manufacturers were contacted, including our SUNBOW FIBERGLASS SLEEVING. Basically, it is said that under the extremely cold conditions of -50 °C, the life of the FIBERGLASS SLEEVING is normal for 2-3 months, the cold resistance is not high, and it is normal for cracks to appear in bending. After SUNBOW received the email, I learned that SUNBOW rushed to guarantee that under the extremely cold conditions of -50°C, the FIBERGLASS SLEEVING will have absolutely no cracks. .

We provide customers with parameters for their reference. The data does not open the hearts of customers, and there is still some hesitation. On the same day, our technical department conducted a quick cold resistance test and broadcast it to customers on the spot. Seeing it with his own eyes and being there, Andy was very surprised by the ultra-high cold resistance performance of SUNBOW FIBERGLASS SLEEVING, and completely trusted SUNBOW FIBERGLASS SLEEVING, and placed a sample test order on the same day.

Less than 3 weeks after the test order, Andy reported that SUNBOW FIBERGLASS SLEEVING is really tailor-made for their Russian customers. No matter how cold the temperature in Russia is, with SUNBOW's FIBERGLASS SLEEVING, their wiring harness will no longer be afraid. SUNBOW has won the absolute recognition and trust of customers by virtue of its superior cold resistance far beyond its peers. Since 2022, FIBERGLASS SLEEVING have been supplied in large quantities for customer wire harnesses.

SUNBOW FIBERGLASS SLEEVING has the following advantages:

1) Certification aspects. It is the most complete manufacturer of glass fiber pipe certification in China. In addition to UL flame retardant, REACH and ROHS environmental protection certification, it also meets the halogen-free certification standards, and there is a third-party authority RP19-025868-SZ certification report, which will never be false.

2) On key raw materials. It is matched with alkali-free glass fiber yarn with a lifespan that is twice as long as that of its counterparts. The whole production process is precisely woven by a fully automatic high-speed knitting machine. Substantially outperform other peers.

3) 1.5 times higher temperature resistance, 2 times higher wear resistance and tear resistance, and more than 2 times higher service life.

SUNBOW FIBERGLASS SLEEVING, try a small order, do not suffer.
