Magnesium Hydroxide Cas No.1309-42-8
Magnesium hydroxide are inorganic compounds with the formula mg(oh)2. for halogen-free packages that require high heat stability, we propose this purity magnesium hydroxide flame retardants.the magnesium hydroxide merchandise in this variety are specially developed to be exact hffr in thermoplastics and rubbers.
The magnesium dihydroxides (mdh) can be used as non-poisonous flame retardants in excessive temperature procedures because of their endothermic decomposition at excessive temperature.
