Product Description:
◎ heat shield ceramic fiber blanket is produced continuously. After acupuncture, the fibers are evenly interwoven, with high tensile strength and no binder.
◎ needled blankets with different bulk density and thickness provide users with a wide range of material selection to obtain the best heat insulation structure and benefits.
◎ heat shield ceramic fiber blanket has good chemical resistance (except hydrofluoric acid, phosphoric acid and strong alkali Na2O, K2O).
◎ the performance of heat shield ceramic fiber blanket is not affected by oil corrosion, and its thermal and physical properties can be restored after drying.
