These products are characterized by the good incombustibility and the high oil-,c corrosion- and fire-resistance and for themmany specifications are available. They are widely used in fireproof partition of cable layers, firproof blockage for large openings, as well as in fireproof covers, fireproof retaining boards and fireproof doors. Type BF partition is made of inorganic non-flammable materials, and type BF-3 compounded with both the organic and the inorganic non-flammable materials.
