Huber Engineered Materials completes acquisition of MAGNIFIN®

The Huber Engineered Materials (HEM) acquisition of RHI Magnesita’s (RHIM) 50% ownership stake in the 50/50 joint venture, MAGNIFIN Magnesia­produkte GmbH & Co. KG (“MAGNIFIN”), signed on May 4, 2021, closed effective December 31.

MAGNIFIN® products are sold globally by Martinswerk GmbH as part of the HEM Fire Retardant Additives (FRA) strategic business unit, which produces a wide range of halogen-free fire retardants, smoke suppressants and specialty aluminum oxides. 
Based in Breitenau, Austria, MAGNIFIN® has been producing premium magnesium hydroxide (MDH) products since 1990. MAGNIFIN® coated and uncoated magnesium hydroxides are environment friendly, halogen-free fire retardants used in a wide range of polymer applications, especially thermoplastic materials and elastomers requiring high processing temperatures in excess of 300 °C. Typical fire retardant applications include energy and local area network (LAN) data cables, automotive wire and cable, engineering thermoplastics (e.g. connectors) and construction membranes.

“This transition is a strong strategic fit with HEM’s mission to own and operate specialty chemical and mineral companies with market leading positions,” says Dan Krawczyk, President of Huber Engineered Materials.

“This step forward demonstrates our commitment towards our customers to support their growth and our clear strategy to grow our halogen-free fire retardant and specialty material business globally,” adds Victor Dean, General Manager of HEM’s FRA strategic business unit.
