Exploring the Role of Mg(OH)2 in Enhancing Flame Retardancy and Tensile Strength of PP/POE Blends

Abstract What about addressing potential challenges related to the dispersion and compatibility of magnesium hydroxide (Mg (OH)₂) within the PP/POE blends, and how might this affect the flame retardancy and tensile strength?Polypropylene (PP) is one of the five plastics widely used in many fields due to its high strength and crystallinity. Polypropylene (PP) burns very quickly due to its completely aliphatic hydrocarbon structure, which limits its scope of application. The use of flame retardant additives in polypropylene (PP) is necessary to minimize the risk of fire due to its inherent flammability. Various types of flame retardants, including halogen, phosphorus, and inorganic compounds, are used due to their flame retardant properties. Magnesium hydroxide typically acts as a flame retardant, producing water to dilute flammable gases. These mineral fillers act in the dense phase and reduce the rate of mass loss and heat release during combustion. This research aims to investigate the effect of magnesium hydroxide (Mg(OH)2, MDH) on the tensile properties and limiting oxygen index (LOI) of polypropylene (PP)/ethylene-butene copolymer (POE) blends.
