Mica Powder CJ-A2 for Industrial Coatings and Plastics

Product Overview‌

Lituo Mica Powder CJ-A2 is a premium-grade muscovite mica engineered to optimize performance in industrial coatings, plastics, and composite materials. With ‌ultrafine 1250 mesh particle size (D50: 10–15 µm)‌ and ‌≥98% crystalline purity‌, this lamellar filler delivers exceptional dielectric strength, UV resistance, and dimensional stability across extreme thermal and chemical environments. Packaged in ‌25 kg anti-static laminated bags‌, CJ-A2 complies with REACH, RoHS, and ISO 9001 standards, making it ideal for automotive, aerospace, construction, and electronics applications.

Designed to replace talc, calcium carbonate, and glass fibers, CJ-A2 enhances mechanical properties while reducing warpage, shrinkage, and processing costs in injection molding, extrusion, and high-build coating systems.
