The Martinswerk ����ýes will become part of HEM’s Fire Retardant Additives (FRA) ����ý. It includes Martinal precipitated and ground alumina trihydrate (ATH) and Magnifin premium precipitated magnesium hydroxide (MHD)—product lines that complement Huber’s existing portfolio of halogen-free FRs and smoke suppressants for plastics. As part of the transaction, Huber will acquire a 50% share in , a joint venture at Breitnau, Austria, which produces MHD. Within the last couple of years, Albemarle doubled capacity there to 44 million/lbs.

This will mark the fourth and largest addition to the FRA ����ý. Earlier this year, Huber acquired the Safire nitrogen and phosphorous FR technology of Belgium’s Floridienne Group and its subsidiary Catena Additives. In 2012, the company bought the specialty hydrate FR ����ý from Almatis, Bauxite, Ark., and in 2010, the Kemguard molybdate FR and smoke suppressant ����ý from Cleveland-based Sherwin Williams.
