The aluminum silicate needled blanket is 2cm thick, usually 7.2m long and 6 1 cm wide. Aluminum silicate needle-punched blanket is a kind of heat insulation refractory material which is made of aluminum silicate as raw material and is specially formed by acupuncture of aluminum silicate long fiber by resistance furnace process. It is characterized by good ductility and strong earthquake resistance. Advantages are white color, regular size and so on. Used for high-temperature thermal insulation in aerospace, steel, petrochemical and electric power.

Aluminum silicate needled felt is made of high-quality flint clay, which is melted at a high temperature of more than 2000 degrees Celsius and solidified with other additives. It has many special properties, strong stability, and does not deform at high temperatures of several thousand degrees Celsius. Therefore, aluminum silicate needled carpets are often used in chemical industry, construction, electronics, aerospace, military industry, air conditioning and refrigeration and other fields.
