High-Performance Magnesium Hydroxide CAS 1309-42-8

Magnesium hydroxide

Magnesium hydroxide, chemical formula Mg(OH)2, formula weight 58.32. White amorphous powder. Alias caustic magnesia, light-burned magnesia, etc. The suspension of magnesium hydroxide in water is called magnesium hydroxide emulsion, referred to as milk of magnesia, and the English name is Magnesium hydroxide. Magnesium hydroxide is a colorless hexagonal crystal or white powder, insoluble in water and alcohol, soluble in dilute acid and ammonium salt solution, and the aqueous solution is weakly alkaline. The solubility in water is very small, but the water-soluble part is completely ionized. The concentration of the saturated aqueous solution was 1.9 mg/L (18°C). Heated to 350 ℃ to lose water to form magnesium oxide. The natural mineral brucite of magnesium hydroxide. Can be used for sugar and magnesium oxide. Because magnesium hydroxide is abundant in nature, and its chemical properties are similar to aluminum, users began to use magnesium hydroxide to replace aluminum chloride for deodorant products. Used as analytical reagents and also used in the pharmaceutical industry.

CAS NO:1309-42-8

Use：

1. Magnesium hydroxide is an excellent flame retardant for plastic and rubber products.

2. Magnesium hydroxide has excellent buffer performance, reactivity, adsorption capacity, thermal decomposition performance, etc. It can be used as a chemical material and intermediate, as well as a green flame retardant and additive for rubber, plastics, fibers, etc. And resin and other polymer materials industry.

3. This product can be used as a flame retardant or flame retardant filler to be added to polyethylene, polypropylene, polystyrene and ABS resin, and has good flame retardant and smoke suppression effects. The added amount is 40~20 parts.

4. Magnesium hydroxide is a new type of filled flame retardant. It releases bound water and absorbs a large amount of latent heat when it is thermally decomposed to reduce the surface temperature of the synthetic material it fills in the flame. It can inhibit polymer decomposition and The function of cooling the generated combustible gas.

5. The product is also used in the manufacture of magnesium salts, the refining of sugar, the pharmaceutical industry, daily chemicals, etc.

6. The milky suspension of magnesium hydroxide is used in medicine as an antacid and a laxative.

Packaging: 25kg bag, 18-20 tons/20GP
