Product introduction
Ceramic fiber blanket product family is a lightweight, thermally efficient ceramic fiber insulation material. At high temperatures, ensures dimensional stability, with the whole can be a good thermal shock resistance. The product line has a wide range of heat resistance and physical properties, can provide for a variety of thermal processing applications proven, effective solutions.
Ceramic fiber blanket is a high strength spun ceramic fiber made by double-sided needling process, which does not contain any binding agents or other ingredients, strengthen the needling process by a corresponding increase in the degree of woven fibers and blanket anti points layer performance, without affecting its flexibility at the same time it has good tensile strength. Fiber blanket has excellent chemical stability, in addition to hydrofluoric acid, phosphoric acid, alkali, the product from the erosion of most other chemicals.
