The modified magnesium hydroxide produced by our company has narrow particle size distribution, good dispersibility, no agglomeration, good compatibility with resin, little influence on the physical and mechanical properties of polymer materials, and excellent flame retardant effect. Different modifiers can be used to modify products according to different customer needs.

Magnesium hydroxide is currently recognized as a high-quality environmentally friendly flame retardant, which has many functions such as low smoke, flame retardant, smoke suppression, anti-dripping, and filling. Its molecular formula is Mg(OH)2 and its molecular weight is 58.32. White powder, non-toxic, odorless, good stability, non-volatile, easy to decompose, non-corrosive equipment, etc., is the first choice for organic polymer polymers to achieve halogen-free flame retardancy.
Because the magnesium hydroxide flame retardant itself is a non-toxic and odorless substance, and its thermal decomposition products water vapor and magnesium oxide are also non-toxic and odorless substances, the magnesium hydroxide flame retardant is identified as an environmentally friendly flame retardant. It is also the first choice for organic compounds to achieve halogen-free flame retardancy.
Because its decomposition degree is as high as 340 degrees or more, it can satisfy that most polymers do not decompose at high temperatures during mixing, processing, and molding. It can be widely used in polyester, epoxy resin, paint, polypropylene, polyacrylonitrile, wire, cable, wood, rubber, paint, PVC, and other fields.
The modified magnesium hydroxide produced by our company has narrow particle size distribution, good dispersibility, no agglomeration, good compatibility with resin, little impact on the physical and mechanical properties of the original polymer material, and a good flame retardant effect. It can be customized according to different customers. If necessary, different modifiers can be used to modify the product.
