Magnesium Hydroxide serves as a flame-retardant filler. Upon thermal decomposition, it releases bound water and absorbs substantial latent heat, lowering the surface temperature of synthetic materials. Meanwhile, it can inhibit the thermal decomposition of polymers and cool the generated flammable gases.
Wire and Cable Insulation: Applied for smoke suppression in halogen-free insulating materials.
Plastics and Rubber: Widely used in polypropylene, polyethylene and PVC to improve flame retardancy.
Construction Materials: Suitable for aluminium composite panels, thermoset plastics and flooring materials.
Electronics: Added to circuit boards and plastic housings for fire prevention.
