    摘要: A powdery flame retardant which is obtained by mixing a flame retardant which is liquid or a viscous solid at ordinary temperature with an inorganic fibrous substance to adhere or adsorb the retardant to the fibrous substance, and which comprises 5 to 70 wt. % the flame retardant and 95 to 30 wt. % the fibrous substance. The powdery flame retardant can be easily handled because it is a powder, and is obtained by a simple and industrially advantageous method. It produces a remarkable effect that the performance of the liquid or viscous flame retardant is not impaired.
