Polyamaide resin molding compn. hveing good inflammability and appearance was prepd. by adding 3-10 wt.% melamine I(R, R1 = H, Me, Et, ethylene, phenyl, tolyl) or its condensate, 2-5wt.% organic phosphate II(R1, R2, R3 = C1-8 alkyl, benzene, C1-3 alkyl-substituted benzene), and 0.5-3 wt.% of powdered talc, clay, kaoline, TiO2, Sb2O3, ZnO(av. diam., 15μ). The inflammability, tensile strength, impact strength and elongation of the mixt. of 90% nylon-6, 6% melamine, 3% triethyl phosphate and 1% TiO2, were 13 sec(UL subject 94), 770 kg/cm2, 5.0 kg cm/cm, 80%, resp.
