Modified magnesium hydroxide

---

■ Brief Introduction

Magnesium hydroxide is an inorganic substance with the chemical formula Mg(OH)₂. It is a white amorophous powder or colorless hexagonal column crystal, soluble in dilute acid and ammonium salt solutions, almost insoluble in water.The part dissolved in water is completely ionized,and weakly alkaline in aqueous solutions. Heating to 350 ℃ to loses water to form magnesium oxide, a natural mineral of magnesium hydroxide, can be used for flame retar.

■ Product Features

• Surface activation treatment has better interfacial compatibilitly compared to untreated powder and is easy to disperse

• Good dispersibility, less prone to agglomeration, and better anti settling performance

• Modified magnesium hydroxide with increased cross-linking

• The modified magnesium hydroxide has a blurry cross section at the group junction, resulting in better dispersion
