In industrial production, construction safety, and high-tech sectors, effective thermal insulation and fire resistance are critical to operational efficiency, energy conservation, and workplace safety. As a high-performance refractory insulation material, alumina silicate needled blanket stands out for its exceptional heat resistance, low thermal conductivity, and excellent flexibility, making it the top choice for industries worldwide. Its reliable performance and wide adaptability establish it as an indispensable material in modern high-temperature applications.
The industrial field is the primary market for alumina silicate needled blanket, especially for high-temperature equipment and kilns. In metallurgy, it is widely used as lining for ladles and aluminum melting furnaces, cutting heat loss by up to 30% and greatly improving energy efficiency. For power plants and chemical facilities, it serves as a durable insulation layer for boilers, reactors, and high-temperature pipelines, withstanding temperatures exceeding 1200°C and resisting corrosive high-temperature environments. In ceramic and glass manufacturing, it stabilizes kiln temperatures, reduces fluctuations, and boosts product yield. With a thermal conductivity of ≤0.038W/(m·K) at room temperature and lightweight properties, it is also ideal for steam pipes and heating systems, helping enterprises lower energy costs and operational expenses.
In construction and fire protection, this material plays a vital role in enhancing building safety. As a Class A non-combustible material meeting international fire standards, it is extensively applied as fire barriers in high-rise building wall cavities, delivering a fire resistance rating of over 2 hours to effectively stop flame spread. It is also the core filling material for fire doors and fire curtains, elevating their fire performance to 1–3 hours. Additionally, it acts as lining for building flues and industrial chimneys, protecting structures from high-temperature damage and reducing heat dissipation, making it a key component of green and safe construction.
Alumina silicate needled blanket also shines in special and emerging industries. In new energy applications such as lithium-ion battery production, it provides reliable insulation for sintering furnaces, mitigating thermal runaway risks. In automotive and marine engineering, it insulates engine exhaust systems and high-temperature components, minimizing heat impact on surrounding parts. Even in aerospace, its superior resistance to extreme temperatures makes it a trusted auxiliary insulation material for ground test equipment and rocket engine peripherals. Its flexibility and customizable thickness (ranging from 30mm to 200mm) allow it to fit complex shapes and meet unique project requirements.
Combining outstanding high-temperature resistance, fireproof performance, and thermal insulation, alumina silicate needled blanket is a cost-effective solution for businesses pursuing safety and energy efficiency.
