J.M. Huber Corp., through its Huber Engineered Materials (HEM) division, has reached an agreement to acquire the Martinswerk mineral flame retardants and specialty chemicals businesses of Albemarle Corp. The transaction is subject to customary closing conditions and is expected to close in early 2016. The Martinswerk businesses will become part of HEM’s Fire Retardant Additives (FRA) business unit.  The acquisition includes: Martinal precipitated and ground alumina trihydrate; Magnifin premium precipitated magnesium hydroxide; a variety of specialty chemical products: Martifin specialty hydrates for paper; Martoxid aluminum oxide, primarily for ceramics; Pergopak flatting agents, primarily for coatings; and Compalox granulated activated alumina. Acquiring these product lines complements Huber’s existing portfolio of fire retardants and smoke suppressants while expanding its geographic presence and reach globally.  As part of this transaction, Huber will also acquire a 50 percent position in Magnifin, a joint-venture at Breitenau, Austria, which produces magnesium hydroxide. The acquisition marks the fourth and largest addition to HEM’s fire retardant additive business in the last five years. Earlier this year, Huber purchased the Safire nitrogen and phosphorous flame retardant technology from Floridienne Group and Catena Additives.  In 2012, Huber bought the specialty hydrate flame retardant business from Almatis and in 2010, the Kemgard flame retardant and smoke suppressant business from Sherwin Williams. www.hubermaterials.com
