Customer's Story Sharing


The Silicone Fiberglass Sleeving can maintain flexibility and resistance to tortuosity at minus 50°C, and only SUNBOW is the only one in China.

For Silicone Fiberglass Sleeving, strong domestic manufacturers can ensure ultra-high pressure resistance, temperature resistance, or insulation and flame retardant performance. SUNBOW is one of these few manufacturers. However, it is required to achieve ultra-high cold resistance and maintain stable bending flexibility in ultra-low temperature environments. There is only SUNBOW in China, and its peers cannot do this. In the insulating casing industry, SUNBOW'sSilicone Fiberglass Sleeving is far ahead, and its peers can only look back.

With the development, the use of fiberglass sleeving has become more and more extensive, which has also increased customers' requirements for some performances of fiberglass sleeving. In the past, customers inquired about Silicone Fiberglass Sleeving and required high temperature resistance to 200 degrees. They have never encountered requirements for cold resistance. When faced with this problem, many manufacturers have not actually done any tests, but they claim that their Silicone Fiberglass Sleeving can meet such strict cold resistance performance, but the actual test is a face, which is vulnerable. In order to get the customer's order and lie to the truth, in fact, there is no ability to do it.

At the beginning of 2020, a well-known heavy truck manufacturer called SUNBOW to inquire about the use of Silicone Fiberglass Sleevings on their drive motors. Because these heavy trucks usually transport goods in cold places, in addition to requiring voltage resistance and flame retardancy, they also emphasize the need for high cold resistance. In the ultra-high cold environment, the bending flexibility should be stable. Prior to this, the customer took samples from many suppliers for testing, but the results were disappointing. Those samples were cracked when they were bent at a low temperature of -50 degrees for less than one month. After a long time of searching and testing, but no satisfaction was found, the customer was very distressed.

We recommended SUNBOW's Silicone Fiberglass Sleeving for customers, and provided the parameters for customers' reference. Seeing that the customer still hesitated, our technical department conducted a quick cold resistance test on the same day and broadcast it to the customer on the spot. I saw it with my own eyes and was on the scene, and the customer was very surprised by the ultra-high cold resistance of SUNBOW's Silicone Fiberglass Sleeving, and placed a trial order of 5,000 meters on the same day.

In mid-April, customers sent feedback that the cold resistance of SUNBOW's Silicone Fiberglass Sleeving was as promised. After a long period of testing in an ultra-low temperature environment, the bending flexibility has been stable, and there is no cracking phenomenon at all. In addition, all aspects of SUNBOW's fiberglass sleeving have met the stringent requirements of customers. Customers are even satisfied with SUNBOW's fiberglass tubes, and they confirm that SUNBOW is their first-tier supplier, supplying large quantities of Silicone Fiberglass Sleevings for their drive motors all year round.

SUNBOW, with 12 years of rich experience, is a professional Silicone Fiberglass Sleeving manufacturer, sincerely does business, seeks truth from facts, and never slaps the face to make you fat. SUNBOW, with a strong R&D team, and technical support of proprietary formulas, produces Silicone Fiberglass Sleeving with outstanding cold resistance, far surpassing its peers. SUNBOW will never falsify, because this is an unquestionable fact, so why do we need to falsify it again?

SUNBOW Silicone Fiberglass Sleeving has the following advantages:
2) Certification aspects. It is the manufacturer with the most complete certification of Silicone Fiberglass Sleevings in China. In addition to UL flame retardant, REACH and ROHS environmental protection certification, it also meets the halogen-free certification standard. There is a third-party authority RP19-025868-SZ certification report, which will never be faked.
2) On key raw materials. It is matched with alkali-free glass fiber yarn with a lifespan of up to 2 times that of the peers. The whole production process is precisely woven by a fully automatic high-speed braiding machine. The outer layer is coated with a foreign big-name silicone oil, combined with the proprietary technology developed by the team, and various aspects of performance. Substantially surpass other peers.
3) The temperature resistance is 1.5 times higher than that of the same peer, the wear resistance and tear resistance are twice that of the same peer, and the service life is more than twice that of the same peer.

It can maintain its flexibility and resistance to tortuosity even at a low temperature of minus 50 ºC, so use SUNBOW Silicone Fiberglass Sleeving.
