The core advantages of this product lie in its superfine particle size and optimized surface treatment, which enables it to achieve uniform dispersion in rubber compounds without agglomeration, thereby enhancing the overall performance of final rubber products. Its high oil absorption rate improves the compatibility between the filler and rubber matrix, reducing the risk of filler segregation during processing. It also reduces the viscosity of rubber compounds, making the mixing and molding processes smoother and more efficient. The product’s low dust content minimizes workplace health hazards, complying with occupational safety standards. Additionally, it provides excellent weather resistance for outdoor rubber products, extending their service life.
Average particle size: 1.0-3.0 μm; Purity (CaCO3): ≥99.2%; Whiteness: ≥94%; PH value (10% slurry): 8.5-9.5; Moisture content: ≤0.15%; Bulk density: 0.7-0.9 g/cm³; Oil absorption value: 20-25 g/100g; Reinforcement coefficient: 0.85; Dust content: ≤0.05%; Packaging: 25kg standard woven bags, 1000kg jumbo bags (palletized for bulk shipment); Surface treated with stearic acid to improve compatibility with rubber matrices.
Primarily used in the production of radial tires, bias tires, and other rubber tire components to improve the wear resistance and load-bearing capacity of tires. It is also widely used in the manufacturing of rubber hoses, sealing gaskets, footwear soles, and industrial rubber parts. The product can replace 20-30% of carbon black in rubber formulations without significantly reducing product performance, effectively lowering the production costs for rubber manufacturers. It is suitable for both natural rubber and synthetic rubber processing, meeting the diverse needs of the global rubber industry.
