Alumina fiber blanket is a blanket-like product made of alumina fiber cotton under specific conditions through dry needle punching process, without any organic binder or other additives.
Products are widely used in high-temperature fields of 1250°C-1500°C in various industries to solve problems such as fire resistance, heat insulation, and fire prevention. It can be used as gap filling and sealing materials in high temperature fields, and raw materials for other high temperature resistant products.
