Description

Magnesium Hydroxide is a high-purity inorganic alkaline powder designed for applications where controlled alkalinity, low smoke generation and thermal decomposition are required.

Our magnesium hydroxide is available in different grades to match the processing requirements of plastics and rubber, industrial wastewater treatment, and flue gas desulfurization.

The product is manufactured with controlled chemical composition and whiteness for industrial applications where consistency between batches is important. Different purity levels and particle forms can be supplied according to the customer's processing method and end use.

For overseas buyers, we provide both standard industrial specifications and application-oriented grades, together with flexible packaging, sample support and export delivery arrangements.

Application

Flame Retardant

 

Magnesium hydroxide is used as a halogen-free flame-retardant filler in plastic and rubber formulations. During thermal decomposition, it releases water and absorbs heat, helping reduce flame propagation and smoke generation.
 

Typical applications include cable compounds, plastic profiles, rubber hoses, fire-resistant sheets and other polymer-based products.

Wastewater Treatment

 

Magnesium hydroxide can be prepared as an alkaline slurry for pH adjustment in acidic industrial wastewater. Its controlled alkalinity allows gradual neutralization during treatment.
 

It can also assist the precipitation of dissolved metal ions in wastewater treatment processes, making it suitable for selected electroplating, mining and chemical-industry wastewater applications.

Flue Gas Desulfurization

 

Magnesium hydroxide slurry can react with sulfur dioxide in combustion flue gas and is therefore used as an alkaline absorbent in desulfurization systems.
 

It is suitable for industrial boilers and other combustion processes where sulfur dioxide reduction is required and magnesium-based treatment is selected.
