    • Commodity name: Aluminosilicate Ceramic Fiber Blanket

    Our aluminosilicate ceramic fiber blanket is a novel lightweight refractory insulation material made from high-purity raw materials that are melted in a resistance kiln

    Product Description

    Our aluminosilicate ceramic fiber blanket is a novel lightweight refractory insulation material made from high-purity raw materials that are melted in a resistance kiln, then processed through techniques such as blowing or spinning, needling, and high-temperature shaping. With a white appearance and uniform dimensions, it is either refractory and heat resistant, or insulating. It contains no organic components and exhibits no volatile substances at high temperatures, making it an ideal energy-saving insulation material for kilns. We offer a wide range of material options with different chemical compositions, densities, and sizes. These products can be applied across various industries for refractory, insulation, and heat preservation purposes.

    Product Features

    ○ Low thermal conductivity and low thermal capacity:

    ○ Excellent thermal stability and thermal shock resistance;

    ○ Excellent chemical stability;

    ○ Excellent heat insulation, fire prevention and sound absorption.
