After a third-party test, the heat resistance (thermal shock test) of Sunbow silicone rubber fiberglass tube is twice that of its peers. This feature cannot be surpassed by domestic counterparts. At the forefront, there are almost no competitors in the country.

    At present, the heat resistance of glass fiber pipes of domestic counterparts is generally low. After testing for about 7 days, there will be cracks and ruptures. This is not to underestimate the peers, but to verify most of the well-known manufacturers, which is a fact. Sunbow has already surpassed this technical level. The heat resistance (thermal shock test) of Sunbow glass fiber casing has reached 480H, no cracks, no cracks, and no oil layer falling off. This is also a fact.

    As early as 2015, a German company found Sunbow to consult Sunbow silicone rubber fiberglass tube through the Internet, and asked about the heat resistance of Sunbow silicone rubber fiberglass tube, and we replied that the existing highest can withstand the 480H test. Customers questioned, "Is it true? I have consulted more than a dozen manufacturers, and none of them passed the 240H heat resistance test." Sunbow is a pioneer in the development of heat-resistant glass fiber sleeves, and has mass-produced products of different levels to Meet customer specific needs. ( PVC tube)

    The customer applies it to the heating plate of the induction cooker, which has high power and generates a large amount of heat. The compound molecules in the silicone rubber are volatile at high temperature when the glass fiber sleeve is used, which will easily affect the heat dissipation and shorten the service life. Therefore, the high temperature resistant silicone rubber fiberglass pipe has become the first choice for customers. After seeing the parameters of the high temperature resistant silicone rubber fiberglass pipe, the customer is still very satisfied and wants to install the machine to verify the practicability of the casing.

    The sample is delivered to the customer within five days, followed by a heat resistance test lasting 480 hours, including aging test, (ie temperature 245℃, 6 hours); high and low temperature cycle test (ie temperature -40℃~200℃ ). The results are as expected. After the thermal shock test for up to 480H, there is no crack or crack, and the oil layer does not fall off. The test result before and after the heat resistance test does not change by more than 2%, which is stable and reliable. ( silicone tube)

    Fiberglass sleeves can lead the domestic counterparts. In addition to high-quality raw materials, combined with proprietary formulas and targeted processes, Sunbow has introduced all automatic yarn beating machines, high-speed braiding machines, and automatic pipe-passing machines. The degree of automation is comparable to that of only 2 factories in China. At the same time, Sunbow is one of the two companies with high-speed knitting machines in China, which makes the delivery time more than 30% faster than that of the peers, and greatly reduces the waste caused by labor and equipment, ensuring quality stability and quality between different batches. reliability. In the past five years, the customer has not replaced the glass fiber sleeve after using it, and placed orders regularly without any other problems.

    It seems that there is no professional silicone rubber fiberglass pipe manufacturer in China that has done better than Sunbow.
