Dolomite Powder 300 Mesh, Packaging Size: 50KG

Dolomite Powder – 300 Mesh
Dolomite Powder (300 Mesh) is a high-quality, micronized mineral powder derived from natural dolomite rock, composed primarily of calcium carbonate (CaCO₃) and magnesium carbonate (MgCO₃). The 300 mesh fineness ensures extremely fine particles that pass through a 300-micron sieve, delivering excellent dispersion, smooth texture, and consistent performance across various industrial applications.

Technical Highlights:

• Mesh Size: 300 mesh (fine powder)

• Composition: CaCO₃ (50–55%), MgCO₃ (40–45%), trace minerals

• Whiteness: 90%+ (depending on source)

• Moisture Content: <0.5%

• Specific Gravity: ~2.85

• Bulk Density: ~900–950 kg/m³

• pH: Neutral to slightly alkaline (8–9)

Key Features:

• Highly refined and consistent particle size distribution

• Exceptional whiteness and brightness for enhanced visual appeal in end products

• Smooth and soft texture for better blending and surface finish

• Chemically stable, non-toxic, and environmentally friendly

• Inert filler with excellent compatibility with resins, binders, and pigments

Industrial Applications:

• Paints & Coatings: Improves opacity, brightness, anti-settling properties, and weather resistance

• Plastics & Rubber: Enhances strength, dimensional stability, and reduces production cost as a filler

• Ceramics & Glass: Acts as a fluxing agent, improves glaze finish, and increases strength of ceramic bodies

• Construction Materials: Used in putty, wall care products, primers, and dry mix mortars

• Agriculture: Functions as a soil conditioner, neutralizing acidic soils and supplying calcium & magnesium

• Chemical Industry: Used in magnesium oxide production and as a feedstock for other compounds

Advantages in Use:

• Fine particle size ensures smooth blending with other raw materials

• Stable color and chemical properties for consistent product quality

• Cost-effective alternative to other mineral fillers without compromising performance

• Enhances durability and performance of finished goods

• Available in various packaging options
