CeramicLooseFiberis made by the melted raw materials at high temperature through resistance furnace, before being blown or spun into fiber. As a neutral and acidic material, except reaction with the strong acid-alkali,refractoryceramic fiber won’t be eroded by other weak alkali, weak acids, or water, oil, steam, or be infiltrated with lead, aluminum or copper, featuring excellent flexibility and elasticity. Ceramic fiber is of smaller density, more than 75% lighter than insulation brick lining or 90% -95% lighter than lightweight castable lining, with thermal conductivity co-efficient to be 1/8 of the lightweight clay brick or 1/10 of lightweight heat-resistant lining (castable), and heat capacity to be 1/10 of both lightweight insulation lining and lightweight castable lining, thus to greatly lower energy loss and deliver significant energy-saving regenerative effects. Meanwhile, the ceramic fiber features a simple construction with no need of baking oven, shortened construction cycle and easy installation.
Characteristics:
Low heat capacity and low thermal conductivity;

Raw material for fiber textile products;
Fillings for wall lining gap in high temperature furnace, heating device;
Raw material wet processed products;
Fiber spraying;
Castables;
Raw material for coatings;
Insulation fillings for corner and complex space
