Alkaline earth silicate fiber blanket (AES fiber blanket) is a soft and white high temperature resistant material which has been developed in recent years. From the appearance, it has no difference from ceramic fiber blanket, but their chemical compositions are different. AES fiber blanket is mainly composed of SiO2, CaO and MgO. Ceramic fiber blanket is made from aluminum silicate fiber. Its main chemical component is Al2O3 and SiO2. Due to the calcium-magnesium structure of AES fiber blanket, it is more environmentally friendly than ceramic fiber blanket. Its fiber has low biopersistence. If people inhale its dust or small pieces of fiber, they stay in human body for a short time and can be dissolved in human body fluid easily, so the product is also called Bio soluble fiber blanket. AES fiber blanket will not cause lung cancer or other lung diseases. It has no harm to people’s health and no harm to environment as well.

AES fiber blanket has the characteristics of low thermal conductivity, high tensile strength, good thermal shock resistance, excellent thermal insulation, low shrinkage and is mainly used as lining material in furnaces, ovens, kilns, boilers and other high temperature resistant equipments. It is widely used in the aerospace, automotive, petrochemical and electrical appliance industries, etc. The blanket also can resist low temperature and be used as cold insulation material. 

AES fiber blanket has been designed for the purpose of replacing ceramic fiber blanket. InChina, many manufacturers can produce this kind of blanket. Most of the AES fiber blankets produced inChinacan resist classification temperature of 1100 degrees C and the continuous working temperature can reach 900 - 1000 degrees C. Its price is only a little higher than the same temperature of ceramic fiber blanket. If customers need higher temperature AES fiber blanket, its price is higher. Today, people pay more and more attention to human health and environment protection. More and more customers in developed countries use AES fiber blanket as the high temperature resistant material instead of using ceramic fiber blanket. If you need refractory fibrous blanket, meanwhile, the temperature can meet your requirement, this blanket is perhaps the best choice for you. With the continuous research and development, AES fiber blanket of higher temperature resistance at lower price can be obtained some day.
