【Abstract】 Polypropylene (PP) materials have been widely studied. However, the usefulness of PP can be limited by its high flammability. Reducing the inherent flammability of PP is normally achieved by incorporating fire retardant additives (FR), such as brominated compounds in combination with antimony trioxide synergists, certain hydrated inorganic compounds such as aluminum hydroxide, Al(OH)3, and magnesium hydroxide, Mg (OH)2. Generally, there is a lack of adhesion between PP and fire retardant additives due to large surface energy differences, resulting in a loss in the mechanical properties. The technique for improvements in flame retardance and mechanical properties of PP/FR has been investigated in the paper.更多还原
