Magnesium Hydroxide Surface Coating - The Necessary Path for Flame Retardant Filler

Magnesium hydroxide and ultrafine brucite are inorganic flame retardant fillers for high-polymer-based materials with a main chemical composition of Mg(OH)2. Magnesium hydroxide flame retardants rely on exothermic chemical decomposition and release of water when heated to achieve flame retardant effects. They possess characteristics such as non-toxicity, low smoke, and stable properties of magnesium oxide generated after decomposition, with no secondary pollution.

The table below shows the influence of different formula modifiers on the mechanical properties of flame-retardant polyethylene materials filled with magnesium hydroxide.
