Crafted from the pinnacle of high-quality alkali-free glass fiber, our fire sleeve showcases an exceptional blend of innovation and durability. The alkali-free glass fiber is meticulously transformed into strands using advanced sand mixing equipment. These strands are then intricately woven into a robust circular tubular embryo tube through a precise, tight 8-shaped track, ensuring unparalleled uniformity in weaving and a superior structural integrity. This masterfully crafted embryo tube is then enveloped in a resilient silicone rubber coating via our state-of-the-art coating cylinder, followed by a vulcanization process in the drying channel. This remarkable product retains its soft, elastic properties even under extreme temperatures ranging from -65℃ to 260℃. Moreover, it can withstand intense heat exposure at 1600℃ for an impressive duration of 15 to 30 seconds. Even when the silicone rubber succumbs to the flames, the fiberglass continues to perform steadfastly under high temperatures. These versatile products find their application in high-temperature environments such as iron and smelting industries, shipbuilding, and the chemical sector. They are ideal for safeguarding cables, fluid pipes, rolling mill cable oil pipes, generators, and electrical voltage equipment. Additionally, they serve as reliable protection in large buildings, hydraulic pressure systems, automotive harness assemblies, and exhaust pipes, offering unmatched safety and performance.
