Bergheim, Germany, 1 November 2018 – Martinswerk, part of the Huber Engineered Materials division of J.M. Huber Corporation, announces a global price increase of up to 15 percent depending on product grade and packaging for its Martoxid® and Compalox® aluminum oxides, Martinal® fine precipitated hydrates and all other alumina trihydrate (ATH) grades effective 1 December 2018 or as current contracts allows.

Prices for MAGNIFIN® magnesium hydroxide will be increased in the mid-single digit percent range. 

Extreme tightness in the supply of chemical grade alumina hydrate has resulted in significant cost increases.  In addition, increases in the costs of other raw materials, energy, CO2 credits and freight are also contributing factors.
