Information Details


Chemical Name:

53% Magnesium Hydroxide Slurry

I. Basic Information

Chemical Formula: Mg(OH)₂

Appearance: Milky white thick liquid, odorless and tasteless

II. Physical Properties

1. Solid Content: Standard range 30%~60%

2. Viscosity: Low viscosity with good fluidity, easy for pumping and formulation

3. Suspension Performance: Resistant to stratification upon standing, excellent storage stability

4. Form: Water-based suspension with favorable flowability

III. Chemical Properties

1. Acidity and Alkalinity: Weakly alkaline with pH value of 9.5~10.5, strong buffering capacity

2. Solubility: Slightly soluble in water, soluble in strong acids, capable of acid-base neutralization reactions

3. Stability: Chemically stable at ambient temperature, resistant to oxidation and deterioration

4. Environmental Friendliness: Halogen-free, non-toxic, heavy-metal-free, generates no smoke or toxic fumes

Applications:

1. Flame Retardant for Rubber and Plastics: Used as an eco-friendly flame retardant filler in plastics, rubbers, cable compounds, paints and coatings.

2. Environmental Treatment: Flue gas desulfurization (thermal power plants / vessels), pH adjustment of industrial wastewater, heavy metal adsorption.

3. Coatings / Papermaking / Textiles: Matting and flame retardancy for coatings; pH adjustment and retention aid for papermaking; flame retardancy and acid removal for textiles.

4. Agriculture: Slow-release weak alkali agent, applied as soil conditioner.
