About usAusChina New Flame Retardants is a join venture company established in 2002 and located in Zibo city, Shandong Province of China. The goal of the company focus on research and development of new serious non-toxic flame retardant, especially Magnesium Hydroxide [Mg (OH) 2].About our productSuper-Fine Mg (OH) 2 is a white crystalline powder manufactured from high quality brucite ore by mechanical and chemical process. The content of Mg (OH) 2 in the raw material is 95% and above. The biggest characteristics of this product is to get a high qualities, thinner and more narrow degree of super-fine Mg(OH)2 powder by using wet stem method rather than dry method as usually used. We use a special chemical treatment method to improve surface modification of Mg (OH) 2 to making it better combine with organic materials. The product has been widely used as flame retardant in plastics, paints, adhesives, sealants and rubber.Details of ProductRaw materialThe raw material we used comes from North part of China, the transportation is very convenient and cost is acceptable. The degree and quality of raw mineral product can be monitored by many different tests.
