Inorganic Material Business
We handle the entire production process of our in-house silica sand, from raw material to finished product.
Aiming for High Quality and High Added Value
Silica sand has long been used as a fundamental material due to its global abundance. We provide safe, reliable, and high-quality sand that meets the diverse needs of today's strict legal and regulatory environments. Our sand is produced in clean, controlled conditions to ensure consistent quality and performance.
We offer products with low metallic impurities, excellent fluidity, and support for small-lot production.
Spherical Materials (Spherical Silica, Fused Silica, Amorphous Silica, Spherical Glass, Glass Bead)
We offer not only spherical silica made from high-purity Australian silica sand, but also various inorganic spherical fillers, including glass-based materials. Spherical silica is highly suitable as a filler due to its excellent heat resistance and smooth dispersibility, making it ideal for applications such as pastes and encapsulants. We precisely control particle size distribution and specific surface area to meet the diverse requirements of our customers.
