CAS 1309-42-8 Magnesium Hydroxide

CAS 1309-42-8 (magnesium hydroxide) is a white amorphous powder that combines the stability of inorganic materials with environmentally friendly properties. Its molecular structure is rich in crystalline water (decomposition temperature 340-490 ℃), which releases water vapor and absorbs a large amount of heat when heated, achieving flame retardant and smoke suppression effects; Simultaneously possessing the reactivity of alkali metal oxides, it can be used in scenarios such as acidic wastewater treatment and flue gas desulfurization. The product has a purity of ≥ 99% and a heavy metal content of<5ppm. It has passed ISO 9001 and ISO 14001 system certification and complies with the GB 25572-2010 food additive standard and the EU REACH regulation.

Physical and Chemical Properties

Application :

Magnesium hydroxide Mg(OH)₂ is widely used as an environmentally friendly flame retardant and functional filler in various industries:

• Wires and cables: Enhance the fire resistance of low-smoke halogen-free (LSHF) cables to meet strict safety standards for building and automotive wiring.
• Copper clad laminates (CCL): Improve the thermal stability and dielectric properties of PCB materials to ensure the reliability of high-frequency electronic devices.
• Composite insulators: Provide anti-tracking and UV resistance in power transmission systems, extending service life in harsh environments.
• Thermal insulation materials: Reduce heat transfer in building insulation foams and fireproof boards, supporting energy-saving designs.
• Other uses: Used as a smoke suppressant in rubber products, neutralize acidic wastewater, and stabilize polymers in automotive parts.
