In this work, aluminum tri hydroxide (I), zinc oxide (II) and their mixture (1:1) (III) were used as flame retardants for unsaturated polyester resin in the weight ratios of (0, 2, 4, 7, 10, and 12) %, by preparing films of (130*130*3) mm in dimensions.
Three standard test methods used to measure the flame retardation which are: ASTM: D-2863 to measure the limiting oxygen index (LOI), ASTM: D-635 to measure the rate of burning (R.B) & ASTM: D-3014 to measure the maximum height of flame (H). Results obtained from these tests indicated that; ATH, ZnO and their mixture have a good effect as flame retardants for unaturated polyester resin. The synergetic effect was the best.
