Discover the pinnacle of thermal protection with our Premium Heat-Resistant Material Insulation Sleeve, meticulously crafted by Ningguo Xinmao Glass Fiber Co., Ltd. This exceptional fire sleeve is engineered from premium, alkali-free glass fibers, renowned for their resilience and durability. These fibers are expertly blended into strands using cutting-edge sand mixing technology, then woven into a seamless, circular tubular structure via a precise 8-shaped track. This ensures unparalleled uniformity and structural integrity. The tubular structure is then meticulously coated with high-grade silicone rubber within specialized coating cylinders, followed by a thorough vulcanization process in our advanced drying channels. This meticulous process endows the sleeve with a remarkable soft elasticity, maintaining its integrity in temperatures ranging from -65℃ to 260℃. In extreme conditions, it can withstand temperatures up to 1600℃ for 15-30 seconds, showcasing its superior resilience. Even when the silicone rubber succumbs to intense heat, the underlying fiberglass continues to perform, making it ideal for use in demanding environments such as iron and steel production, smelting, marine applications, and chemical processing. Our versatile insulation sleeve is perfect for safeguarding cables, fluid pipes, rolling mill cables, oil pipes in generators, electrical voltage equipment, large-scale buildings, hydraulic systems, automotive harness systems, and exhaust pipes, ensuring optimal performance and safety.
