FLAME RETARDANT COMPOSITION FOR POLYURETHANE, FLAME RETARDANT POLYURETHANE AND FLAME RETARDANT POLYURETHANE FOAM PRODUCED USING SAME

摘要

Provided are: a flame retardant composition in which red phosphorus, which has a high flame retardant effect, is evenly dispersed and which has excellent storage stability after mixing with other materials, as a flame retardant for polyurethane, in particular for polyurethane foam; and flame retardant polyurethane and flame retardant polyurethane foam which are produced using the same. This flame retardant composition comprises (A) 3-50 mass% of red phosphorus and (B) 0.2-15 mass% of an anti-settling agent. The anti-settling agent is selected from carbon black, fine powder silica, a hydrogenated castor oil wax, a fatty acid amide wax and organic clay. The flame retardant polyurethane is produced by adding the flame retardant composition for polyurethane.
