Stearic Coated Calcium Carbonate

At Rubel Mineral, we offer Stearic Acid Coated Calcium Carbonate Powder designed specifically to enhance processing performance while ensuring both cost-efficiency and workplace safety.

Product Overview:

Stearic acid coating is applied to the surface of fine calcium carbonate particles to improve their dispersion, flowability, and compatibility with polymer-based applications. This surface modification results in a hydrophobic (water-repellent) material, making it especially suitable for use in plastic, rubber, cable, and masterbatch industries.

Key Benefits:
  • 💰 Reduces Raw Material Cost: Improved dispersion means less energy is required during mixing, leading to lower production costs and more efficient material usage.
  • 🛡️ Enhances Worker Safety: The coating significantly reduces airborne dust during handling, contributing to a cleaner and safer working environment.
  • ⚙️ Improves Processing: Enhances blending with resins, improves extrusion and molding performance, and reduces wear on machinery.

Applications:

  • Plastic Industry – In masterbatches, PVC compounds, and polyethylene processing

  • Rubber Industry – As a functional filler for better elasticity and finish

  • Cables and Wires – Enhances insulation and mechanical strength

  • Adhesives and Sealants – Improves thixotropy and stability
