According to different production processes, it can be divided into spinning needle felt and blown needle felt; According to the different raw materials and formulas, it can be divided into: ordinary type (STD), high purity type (HP), high aluminum type (HA), zirconium aluminum type, standard type, and zirconium-containing type (ZA). In fact, this classification is also different in application temperature. The common applicable temperature is around 1000 degrees Celsius, the better one is around 1200 degrees Celsius, and the higher one is around 1400 degrees Celsius.

The biggest function of aluminum silicate insulation blanket is that it has a good thermal insulation effect, especially when it is used in boilers with high temperature. Sometimes, rock wool and glass wool products cannot reach the working temperature of 1000 degrees, so it needs products such as aluminum silicate insulation blankets to meet the requirement.
