Product Details

Product Details: 

For halogen-free applications that require high heat stability, we  recommend our high purity magnesium hydroxide flame retardants.The magnesium hydroxide products in this range are specifically developed to be excellent halogen free flame retardants in thermoplastics and rubbers.

 

Magnesium hydroxide are inorganic compounds with the formula Mg(OH)2. The magnesium dihydroxides (MDH) can be used as non-toxic flame retardants in high temperature processes due to their endothermic decomposition at high temperature.

MDH start to decompose endothermically at temperatures above 340 oC, which results in the formation of magnesium oxide (MgO) and water (H2O). When this occurs MDHprovides flame retardancy in three steps.firstly ,The release of water results in cooling and decreased pyrolysis of the polymer.secondly,The released water dilutes the fuel/oxygen ratio. Last ,The MgO that is generated works as a protective layer that provides a smoke suppressant effect.
