CERAMIC FIBER BLANKET

DAYAWOOL ceramic fiber blanket presents unparalleled refractories and thermal insulation due to its long spun fiber needling technique. These blankets offer superior insulating performance, flexibility and resilience. ceramic fiber blanket products are unaffected by most chemicals (except hydrofluoric & phosphoric acids and concentrated alkali). Thermal and physical properties are retained after drying following wetting by oil, steam or water. ceramic fiber blankets are completely inorganic, so there are no fumes when heating for the first time.
