Preparation Flame Retardant Plastic by Using Non Halogen Micro MaterialsAbbas K. Ibrahim Hameed K. Abbas Muntaha N. Thwene E-Mail : abbaskhaleel75@yahoo.comAbstract In this research , we used inorganic environmental friendly additives to decrease the flammability and increase the flame retardant of poly propylene .We used Magnesium hydroxide (Mg(OH)2) and magnesium hydroxide with fumed silica (SiO2)Together to study the synergetic effect for these compounds to increase flame retardant ,and we tasted the success of this tow compounds by reliable methods to see how successful are these compounds to decrease the flammability and these methods are (ASTM),from the results that we gut from these tests we find that the best result is (50%) from magnesium hydroxide and it is more effective to decrease the flammability for poly propylene , and the synergistic effect for fumed silica with magnesium hydroxide gave a better result with (8%,5%) from fumed silica (SiO2) with (Mg(OH)2), and there is a compatibility between the additives and the poly propylene ,and it is considered as a primary constituents to get the best results to decrease the flammability for the composites . Whenever the diffusion of the additives particles was high, the results will be better.
