Product description

Integrating refractory, heat insulation and heat preservation, refractory fiber blanket is a refractory and heat insulating material made from aluminum silicate using resistance furnace needle punching process. It has good chemical stability, low heat capacity, good thermal stability and Thermal conductivity is low.

Application of refractory fiber blanket

Refractory fiber blanket used in the chemical industry, construction industry, electronics industry, kilns, industrial furnaces, high-temperature equipment, high-temperature pipelines and other fields for thermal insulation.

Advantages of refractory fiber blanket

◆ High temperature resistance, the maximum operating temperature can reach 1300℃.

◆ Low thermal conductivity and good thermal insulation performance. When used under the same conditions, the thermal conductivity of aluminum silicate products is more than 30% lower than other insulation materials.

◆ It has good sound absorption and sound insulation performance, and has good sound attenuation and sound insulation effect.

◆ It has good electrical insulation and high dielectric constant; it can be used as high-frequency insulating material.
