Ultracal is a high-performance, ultrafine grade of calcium carbonate (CaCO₃) processed to achieve extremely small particle sizes—typically between 0.1 and 10 microns. Its enhanced surface area, brightness, and purity make it a versatile functional filler and performance booster across multiple industries.
KEY CHARACTERISTICS
Physical Characteristics
1. Particle Size: Ultrafine particles ranging from 0.1–10 microns.
2. High Surface Area: Improves reactivity, dispersion, and bonding in end-use applications.
3. Color: Naturally bright white, contributing to superior opacity and finish.
4. Density: Typically between 2.7–2.9 g/cm³.
Chemical Characteristics
1. Chemical Formula: CaCO₃ (Calcium Carbonate).
2. Purity: High-purity grade suitable for industrial, cosmetic, and some regulatory-approved applications.
3. Reactivity: Enhanced reactivity due to its finely ground structure and large surface area.
APPLICATIONS
1. Fillers & Extenders
Widely used in plastics, paints, coatings, adhesives, and sealants to improve strength, opacity, and processing efficiency.
2. Paper & Pulp
Serves as both a filler and a coating agent, increasing brightness, smoothness, printability, and bulk.
3. Cosmetics & Personal Care
Used in products such as toothpaste, face powders, and skincare formulations for its mildness, whiteness, and absorbency.
4. Pharmaceuticals
Functions as an excipient—adding bulk, improving stability, and enhancing product texture and delivery.
5. Food & Beverages
Used as an approved additive in certain food and beverage applications (depending on regulatory standards).
ADDITIONAL FEATURES
1. Dispersion: May require proper dispersion techniques due to ultrafine particle size.
2. Abrasion Resistance: Offers excellent hardness, contributing to improved abrasion resistance in composites.
3. Thermal Stability: Stable at temperatures up to 800°C, suitable for high-temperature processing and formulations.
