Abstract

Abstract In this work, the effect of four types of inorganic phosphorus salts on flammability for polyester and epoxy resins has been studied in the weight ratios of (0.5, 1.5, 2.5 & 3.5%) by preparing films of (130×130×3) mm3 in diameter, Three standard tests method were used to measure the flame retardation which are; ASTM: D-2863, ASTM: D-635 & ASTM: D-3014. The results obtained from these tests indicated that additive IV has high efficiency as a flame retardant, self-extinguishing (S.E), occurred at the percentage 0.5% for unsaturated polyester resin and the percentage 1.5% for epoxy resin. Non-burning (N.B), occurred at the percentage 2.5% for unsaturated polyester resin and at the percentage 3.5% for epoxy resin. Additives I and II show low effect on retard combustion in both resins.
