S1 d0 (Over 90% Stone core content) and EN 13501 – 1 B S1 D0 ( Over 70% Stone core content).
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.
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.
