Global Magnesium Hydroxide Market - Growth Drivers
Rising Demand for Magnesium Hydroxide in Wastewater Treatment
Rising demand for magnesium hydroxide in wastewater treatment due to need for high quality and clean water is expected to drive the market growth. Magnesium hydroxide is highly alkaline in nature that helps to reduce the sludge volume in water. Growing population base rate, ongoing urbanization, and growing oil & gas industry around the globe is also expected to drive the market growth. According to the American Society of Civil Engineers, the estimated wastewater treatment spending in the U.S. was increased to US$ 78 Billion by 2025 from US$ 40 Billion in 2010.
Global Magnesium Hydroxide Market - Market Opportunities
Increasing Demand for Magnesium Hydroxide from the Electronics Industry
Increasing demand for magnesium hydroxide from the electronics industry where it is used as a protective film for plasma display screens is expected to drive the market growth. Moreover, high purity grade of magnesium hydroxide is also used in the development of thin-film semiconductors and researchers are investigating other similar electronic application of magnesium hydroxide that can drive the market growth over the forecast period.
Global Magnesium Hydroxide Market – Restraints
Disadvantage of magnesium hydroxide are expected to hamper the market growth of magnesium hydroxide.
Major disadvantage of magnesium hydroxide is that effective flame retardancy requires high loading levels of metals that is expected to restrict the market growth. Raising the loading of inorganic metal hydroxides leads to decrease in physical and chemical properties of metals, and this can impact the thermal and flame retardancy properties.

Global Magnesium Hydroxide Market- Trends
Acquisition and merger for magnesium hydroxide by the manufacturer of flame retardant is a major trend in the global magnesium hydroxide market. Magnesium hydroxide is considered as a potential alternative to halogenated flame retardant, and thus, products manufacturers are extremely motivated to seize the possibilities for growth in magnesium hydroxide. This ongoing trend is expected todrive the market growth over the forecast period. For instance, in December 2015, Huber Engineering Materials, acquired Albemarle Corporation’s Martinswerk, a mineral flame retardants and specialty chemical business that includes Magnifin, a premium precipitated magnesium hydroxide product line.
Increasing focus of manufacture for expanding the production facility of magnesium hydroxide is expected to drive the market growth of magnesium hydroxide. For instance, in January 2025, The Board of Directors of MAGNIFIN Magnesia products approved the preparatory work for the construction of a second MAGNIFIN Magnesiaprodukte production site. This planned significant investment is driven to meet rising global demand for high-purity, halogen-free magnesium hydroxide fire retardants. Therefore, increasing initiatives by the manufacture for meeting the rising demand for magnesium hydroxide is expected to drive the market growth.
