製品説明

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.

China manufacturer Taixing can provide high purity CAS 1309-42-8 Magnesium Hydroxide. This product is often used in CCL, low smoke cables, insulators and thermal insulation materials. Our products are ISO certified and quality is guaranteed. Bulk pricing. Inquire now!
