該產品具有難燃性、耐腐蝕、耐油、耐火、質輕、規格型號多等特點，適用于電纜層之間的防火分隔及大孔洞防火封堵，也可用于制作各類防火罩蓋、防火擋板和防火門。
BF型產品由無機不燃材料制成，BF-3型產品由無機和有機難燃材料復合而成。
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.
