Prepared through special light calcination technology, it has ultra-high specific surface area and iodine adsorption value, with rich surface active sites, which can cross-link with various organic polymers. As an activator in rubber processing, it can significantly improve the vulcanization speed and cross-linking density, and in adhesives, it can quickly cure and improve bonding strength. It also has excellent flame retardant and smoke suppression performance, meeting the market demand of environmental protection flame retardant materials.
Purity ≥93.0%, specific surface area 50-100 m²/g, iodine adsorption value 80-120 mg/g, loss on ignition ≤4.0%, particle size distribution of 200-300 mesh, pH value 9.5-11.5, calcium oxide content ≤1.5%, bulk density 0.3-0.6 g/cm³. Packaged in moisture-proof woven bags, 25kg per bag, passed ISO 9001 quality system certification, and can adjust activity parameters according to customer needs. Each batch is tested for adsorption performance and particle size to ensure product stability.
Mainly used as vulcanization activator for rubber products, adhesive for chloroprene rubber, flame retardant and smoke suppression auxiliary agent for plastics, adsorbent for sewage treatment, auxiliary agent for antacids in pharmaceutical industry, and thickener for ink coatings. It adapts to the production needs of rubber processing, adhesive, environmental protection, pharmaceutical, coating and other industries, especially suitable for high-performance rubber and adhesive production lines.
