Magnesium hydroxide

Magnesium hydroxideThe chemical formula is Mg(OH)2 with solid,crystalline or amorphous powder,insoluble in water,insoluble in alkaline solution,oluble in dilute acid and ammonium salt solution,decomposed to magnesium oxide and water by heating the initial decompositiontemperature is 340℃ the decomposition is fastest at 430℃.


We adopting the advanced international technology,processed by reaction synthesis,filtering,washing,drying processes,the content more than 99%.
The product is sate and nontoxic,nonhazardous to the environment,does not belong to the flammable,explosive product.The quality of Magnesium hydroxide is better than other similar product.


As the end product can be used directly in the flame retardant,electronics, medicine,food and other industries.
The product as an excellent flame retardants and filers can be widely used in
EVA,PP,PVC,PS,HIPS and ANS plastic,can also be used in unsaturated polyester paints and coatings.
