Mica Powder CJ-A5 for High-Performance Coatings and Plastics
Product Overview
Lituo Mica Powder CJ-A5 is a cutting-edge, ultra-refined muscovite mica designed to meet the rigorous demands of advanced coatings and high-performance plastics. With an ultrafine 3000 mesh particle size (D97: 3–5 µm) and ≥99.5% crystalline purity, this lamellar filler sets new benchmarks in corrosion resistance, thermal management, and surface finish quality. Packaged in 25 kg vacuum-sealed, moisture-proof bags, CJ-A5 complies with REACH, RoHS 3.0, and ISO 9001:2015 standards, making it ideal for aerospace coatings, automotive composites, electronics encapsulation, and flame-retardant polymers.
Engineered to outperform conventional fillers like silica, talc, and kaolin, CJ-A5 enables 30% lighter formulations, 50% faster curing cycles, and extended product lifespans in extreme environments ranging from -60°C to 350°C.
