High pure ceramic fiber blanket with heat insualtion

Specifications

Aluminum silicate ceramic fiber blanket,refractory ceramic fiber blanket  is manufactured from aluminum silicate fiber bulk spinning from kaolinite, alumina silicon dioxide and zircon sand, which been series processing of needling ,cutting and rollings, including 1260°C Standard, 1260°C High pure, 1360°C High Aluminum, 1430°C Zirconium ceramic fiber blanket.

The ceramic fiber blanket with the advantage of uniform quality, smoothly surface ,pure white color, completely inorganic ,good tensile strength, toughness and fiber structure, so there are no flames when heating for the first time , The working temperature ranges from 950°C to 1430 °C.
