High-purity Ceramic Fiber Blankets

High-purity ceramic fiber blankets are thermal insulation and refractory materials made from aluminum silicate, formed by special long-fiber needling. This material can be used stably for extended periods at high temperatures of 1000–1250℃ without aging; it is soft, flexible, and does not expand when heated, allowing for easy cutting and bending during installation. It also possesses excellent resistance to chemical corrosion, vibration, sound insulation, and electrical insulation properties, making it suitable for insulation layers in various high-temperature equipment. The product offers excellent fire resistance and thermal insulation, along with multiple advantages such as material and fuel savings, convenient construction, reduced investment costs, reduced equipment weight, and thinner insulation layers.
