摘要 |
Disclosed is a red phosphorus flame retardant comprising a fine red phosphorus powder subjected to a surface modification treatment, said fine red phosphorus powder consisting of spherical red phosphorus particles and/or agglomerates thereof directly obtained by the thermal conversion of white phosphorus in the presence of a dispersant and has an average particle size of 10 .mu.m or smaller and of which at least 80% by weight is accounted for by particles having particle sizes of 20 .mu.m or smaller, said flame retardant having an average particle size of 15 .mu.m or smaller, with the particles having particle sizes of 35 .mu.m or smaller accounting for at least 80% by weight of the flame retardant; and a nonflammable resinous composition composed of a synthetic resin and the red phosphorus flame retardant. |
