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.
