Crafted with precision, the Fire and Thermal Insulation Protection Sleeve from Ningguo Xinmao Glass Fiber Co., Ltd. is engineered using premium alkali-free glass fiber. This high-quality fiber is expertly formed into strands via advanced sand mixing technology and intricately woven into a circular tubular embryo tube. Our unique weaving process, characterized by a meticulous tight 8-shaped track, ensures unparalleled uniformity and structural integrity. The embryo tube is then enveloped in a robust layer of silicone rubber, applied through a specialized coating cylinder, and skillfully vulcanized in our state-of-the-art drying channel. This exceptional sleeve retains its soft and elastic properties across a remarkable temperature range of -65℃ to 260℃. Furthermore, it withstands extreme temperatures up to 1600℃ for 15 to 30 seconds, demonstrating its resilience even when the silicone rubber is subjected to high heat. The underlying fiberglass remains steadfast, making it an ideal choice for high-temperature environments such as ironworks, smelting operations, marine applications, and chemical processing zones. Its versatility extends to safeguarding cables, fluid pipes, rolling mill cable oil pipes, generators, electrical voltage equipment, large buildings, hydraulic systems, automotive harnesses, and exhaust pipes, offering comprehensive protection in demanding conditions.
