Product Description

Product Description:
◎Ceramic fiber blankets are produced continuously. After needle punching, the fibers are evenly interwoven, with high tensile strength and no binding agent.
◎Needle-punched blankets with different bulk densities and thicknesses provide users with a wide range of materials to obtain the best thermal insulation structure and benefits.
◎Ceramic fiber blanket has good resistance to chemical attack (hydrofluoric acid, phosphoric acid and strong alkali Na2O, except K2O).
◎The performance of ceramic fiber blanket is not affected by oil erosion, and its thermal properties and physical properties can be recovered after drying.
