Magnesium Hydroxide (MDH) Flame Retardant
Featured inFlame Retardants
Magnesium hydroxide (MDH) is an inorganic, halogen-free flame retardant and smoke suppressant that decomposes endothermically at 300–320 °C, releasing water and forming a stable magnesium oxide char layer. Its higher decomposition temperature compared to ATH makes it suitable for engineering thermoplastics processed above 200 °C, including polyamides, polypropylene, and XLPE. MDH is widely used in high-temperature cable insulation, automotive parts, and construction materials requiring UL94 and IEC 60332 compliance.
