Magnesium Hydroxide (CAS No. 1309-42-8) is a high-performance industrial-grade inorganic flame retardant with stable quality and reliable performance. Our product has a whiteness of up to 92%, fine particle size, uniform distribution, and excellent processing stability, making it widely used in PVC, PP and other polymer materials. It is a green, halogen-free and environmentally friendly additive that meets modern industrial requirements for safety, environmental protection and high efficiency.

Properties & Flame Retardancy

With high whiteness, this magnesium hydroxide product can maintain bright color and good appearance in PVC and PP products, reduce the use of toners, and improve product quality and market competitiveness. It has excellent flame retardant effect: when heated, it decomposes endothermically, absorbs a lot of heat, releases water vapor to reduce the surface temperature of the material, dilute combustible gas, and form a dense magnesium oxide protective layer to isolate oxygen and inhibit flame spread. It does not produce toxic or corrosive gas, low smoke, environmental protection and safety, in line with EU environmental directives and industry flame retardant standards.

Applications & Compatibility

In the plastic and rubber industry, it is especially suitable for wire and cable, pipe, sheet, profile and other products. It can improve the flame retardant grade of materials without significantly reducing the mechanical properties of the material, with good compatibility and dispersion, not easy to agglomerate, easy to mix and process. At the same time, the product has stable chemical properties, long storage time, low corrosion to equipment, and can reduce production costs.

As an environmentally friendly alternative to traditional halogen flame retardants, 92% whiteness industrial grade magnesium hydroxide is safe, efficient and versatile. It is an ideal flame retardant additive for PVC, PP and polymer materials, and is widely recognized in construction, electronics, automotive, home appliances and other fields.
