Magnesium Hydroxide Industrial Grade and Pharma grade CAS 1309-42-8

  Product Detail  

We offer high-purity ​​Magnesium Hydroxide Powder​​ (Mg(OH)₂), a versatile white crystalline/amorphous powder with exceptional thermal stability (decomposes at 340–490°C). Insoluble in water but soluble in dilute acids, the magnesium compounds serve as premium raw materials for flame retardants, pharmaceuticals, food additives, and advanced industrial applications. With ≥98% assay and low impurity levels (e.g., ≤0.005% Fe₂O₃), our magnesium hydroxide powder ensures superior performance across diverse sectors.

Chemical Composition:

High-purity magnesium hydroxide can be directly used as a terminal product in flame retardant (steel, metallurgy, chemical, plastic, rubber), electronics, medicine, food and other industries. The first choice of high-quality raw materials for high-end magnesium oxide products such as pharmaceutical grade magnesium oxide, food grade magnesium oxide, and silicon steel grade magnesium oxide. As an excellent flame retardant and filler, this product can be widely used in EVA, PP, PVC, PS, HIPS, ABS plastics, and can also be used in unsaturated polyesters, paints and coatings. Bulk supplements magnesium hydroxide is also used in magnesium salt manufacturing, sugar refining, pharmaceuticals, tooth powder, thermal insulation materials, wires and cables, conveyor belts, air guides, electrical equipment, glass fiber reinforced plastics and paints, etc. It is an environmentally friendly

​​High Purity & Consistency​​

• ≥98% Mg(OH)₂ content with ultra-low impurities (As ≤0.0003%, CaO ≤0.05%), pure magnesium hydroxide powder is ideal for sensitive applications like pharmaceuticals and food additives.

• Strictly controlled production process ensures batch-to-batch stability.

​​Exceptional Thermal Stability​​

• Decomposes at 340–490°C, making it an effective flame retardant for plastics (EVA, PP, PVC) and synthetic resins.
