Kulubrite 5

Kulubrite 5 is an ultra-fine, floated, dry calcium carbonate filler produced by Idwala Carbonates, featuring a particle size ((d_{50})) of approximately 5.5 microns. It is primarily used as a functional filler and extender in industrial applications to enhance performance and reduce costs.

Primary Uses and Applications:

Paints and Coatings: Used to improve opacity, whiteness, durability, and gloss retention.
Plastics and Polymers: Acts as a filler to enhance mechanical properties like stiffness and impact strength in PVC, polypropylene, and polyethylene. It also aids in reducing cooling times during production.
Rubber and Elastomers: Used in tires, seals, gaskets, and hoses to improve wear resistance.C
onstruction Materials: Used in sealants, putties, and cement formulations for better stability and color.
Paper and Ink: Used as a filler or coating pigment to improve smoothness, brightness, and print quality.
Chemical/Industrial Applications: Used as a reagent, fluxing agent, or abrasive (e.g., in cleaning pastes).

Key Characteristics:
High Purity & Brightness: Beneficiated through floatation for maximum whiteness.
Excellent Dispersion: Allows for consistent, smooth, and high-quality finishes.
Particle Size: (d_{50}) of 5.5 microns ((45) down to (0.6) micron range for the general Kulubrite range).
Kulubrite 5 is often used in situations requiring a balance between fine particle size for superior finish and high filler loading for cost-effectiveness.

Kulubrite 5

Our Floated dry calcium carbonate products contained in our Kulubrite product range have been beneficiated through floatation resulting in a brighter, high purity calcium carbonate with particle sizes ranging from 45 micron down to 0.6 micron.

These products are ultra-fine, white extenders with pigmentary properties and good dispersion.

They are used in the paint, chemical, ceramic, plastic and paper industries.
