Laurel Polycrystalline Fiber Bulk is a loose-fill insulation material composed of advanced alumina-silica fibers, designed to withstand temperatures up to 1600°C. Ideal for complex industrial applications, it offers exceptional thermal resistance, low heat conductivity, and chemical stability. Its loose structure allows easy shaping and filling of irregular spaces, reducing installation complexity while maintaining energy efficiency. Environmentally friendly and non-toxic, this bulk insulation is widely used in furnaces, pipelines, and high-temperature equipment to prevent heat loss and enhance operational safety.
