The solid mineral  magnesium hydroxide, with the chemical formula Mg(OH)2  is a common alteration product of periclase in marble; a low-temperature hydrothermal vein mineral in metamorphosed limestones and chlorite schists; and formed during serpentinization of dunites. It is often found in association with serpentine, calcite, aragonite, dolomite, magnesite, hydromagnesite, artinite, talc and chrysotile.

Advantages of Magnesium Hydroxide

 Filler and Flame Retardant/Smoke Suppressant in one product
 Environmentally Acceptable
 Halogen Free
 Non-Corrosive
 Reduces Smoke Density
 Non-Volatile
 Largely Inert
 Thermally Stable up to 340º C and thereafter undergoes Endothermic Decomposition releasing Water

What is Endothermic & Exothermic Reaction ?


LDPE (Low density Polyethylene) is a hydrocarbon material which exhibits exothermic reaction by releasing energy  when exposed to heat.  Mg (OH)2 is a natural mineral which exhibits Endothermic reaction by absorbing heat when exposed to energy/ heat.
