Dolomite Powder For Plastic Film Blowing

Product Overview: High-Purity Superfine Calcium Carbonate

Industrial-Grade Superfine Calcium Powder for High-Performance Applications

In latex paint formulations, our superfine calcium powder significantly enhances coverage, hardness, and resistance to environmental degradation. It optimizes film-forming properties, resulting in a durable, long-lasting finish that maintains its aesthetic appeal over time.

Our superfine calcium powder is sourced from high-purity natural limestone deposits and processed using advanced grinding and classification technologies. This ensures a consistent particle size distribution, high brightness, and superior dispersibility, making it suitable for demanding applications in the paint, paper, and construction industries.

Applications in Latex Paint and Decorative Coatings

As a functional extender, superfine calcium powder improves pigment spacing and dispersion, leading to enhanced color development and gloss control. Its narrow particle size distribution contributes to a smooth film surface and reduced surface porosity, which directly improves dirt pick-up resistance and washability.

• Increases hiding power and opacity, effectively reducing the required amount of titanium dioxide.
• Enhances scrub resistance and abrasion resistance for long-lasting interior and exterior finishes.
• Provides excellent weatherability and UV resistance, preventing chalking and fading over time.
• Improves the overall rheology and workability of the paint formulation.

Enhancing Fire Safety with Superior Flame Retardancy

In fireproof coatings, our superfine calcium powder delivers exceptional flame retardancy and thermal stability. Its high decomposition temperature and endothermic properties make it an ideal component for passive fire protection systems, providing critical time for evacuation and structural protection.

In intumescent and fire-retardant coating formulations, our superfine calcium powder acts as a synergist, promoting char formation and enhancing the thermal barrier. It dilutes combustible materials and absorbs heat during decomposition, slowing the spread of flames and protecting the underlying substrate.

• High thermal stability ensures performance integrity even under extreme fire conditions.
• Improves adhesion and cohesive strength of the protective char layer.
• Compatible with various binder systems, including acrylic, epoxy, and polyurethane resins.
• Contributes to a dense, uniform char structure that minimizes heat transfer.

Optimizing Paper Quality and Production Efficiency

In the paper industry, our superfine calcium powder serves as a premium filler and coating pigment. It significantly improves paper brightness, opacity, and smoothness while reducing the overall cost per ton. Its high purity guarantees minimal abrasion to forming fabrics and doctor blades, extending equipment life.

• Enhances ink receptivity and printability for sharp, vibrant image reproduction.
• Acts as an excellent filler for improving bulk and stiffness without increasing basis weight.
• Replaces more expensive pigments and fillers, providing significant raw material cost savings.
• Improves drainage and drying efficiency during the papermaking process.
