Crafted with precision, the Advanced Thermal Insulation Sleeve by Ningguo Xinmao Glass Fiber Co., Ltd. is comprised of the finest high-quality alkali-free glass fiber. The fibers are expertly combined into robust strands using state-of-the-art sand mixing equipment. These strands are then intricately woven into circular tubular embryo tubes using a precise 8-shaped track methodology, ensuring both uniformity in weaving and structural integrity. To further enhance its resilience, the embryo tube is meticulously coated with durable silicone rubber through an advanced coating cylinder and subsequently vulcanized within a specialized drying channel. This process endows the sleeve with an impressive capability to maintain its soft, elastic properties across a vast temperature range of -65℃ to 260℃. Furthermore, it demonstrates remarkable endurance, withstanding temperatures as high as 1600℃ for up to 30 seconds. Even when the silicone rubber succumbs to extreme heat, the resilient fiberglass continues to perform. These sleeves are versatile and indispensable across various high-temperature industries, including iron and steel manufacturing, smelting, marine operations, and chemical processing. They provide exceptional protection for cables, fluid pipes, rolling mill cable oil pipes, generators, electrical voltage equipment, large-scale buildings, hydraulic systems, automotive harness systems, and exhaust pipes, ensuring safety and efficiency in the most demanding environments.
