We handle products from MMMS, which reacts and refines salt-rich groundwater and dolomite to produce magnesium hydroxide and other materials derived from seawater. "Synthetic Magnesium Hydroxide" is a non-halogen, environmentally friendly, and non-corrosive flame retardant. It is widely used as a natural hydrated flame retardant alongside aluminum hydroxide. We also offer "sulfonate-based flame retardants" from Arichem, which has been selling specialty chemicals to a wide market for over 40 years. 【Features】 ■ Non-halogen and environmentally friendly ■ Highly non-corrosive ■ High cost competitiveness due to concentrated production of two varieties ■ Usable in applications where environmental measures are important, such as wire coating agents ■ Customizable for particle size and surface treatment agents *For more details, please refer to the catalog or feel free to contact us.

"ER fluid" is a fluid that solidifies when a voltage is applied. Under an electric field, particles align, resulting in an increase in apparent viscosity. When the electric field is applied, viscosity increases, and when the electric field is removed, viscosity decreases, demonstrating this effect. Additionally, utilizing the characteristics of ER fluids, various applications such as mechanical elements and vibration control are expected to be developed. [Features] - Stress (fluid viscosity) can be electronically controlled by the strength of the voltage. - Applying an electric field → viscosity increases. - Removing the electric field → viscosity decreases. - Viscosity changes are fast, highly responsive, and reversible. *For more details, please refer to the catalog or feel free to contact us.

"Metallic silicon" is a semiconductor with high thermal conductivity that improves the heat dissipation of plastics.

"Wollastonite" is a natural mineral that is produced in white, needle-like or lump forms. It is mainly used as a ceramic raw material for tiles and porcelain, and has since been widely used in construction materials as an asbestos substitute. The chemical composition of "Wollastonite" is stable, making it ideal for applications that require insulation and mechanical properties. Unlike chemically manufactured synthetic silica, its crystals are thin and long needle-like structures, which maintain these characteristics even when ground into a fine powder. Additionally, it has a glossy white appearance and does not discolor or fade. [Features] ■ Ideal for applications requiring insulation and mechanical properties ■ Glossy white appearance with no discoloration or fading ■ Improved flexural modulus and tensile strength *For more details, please refer to the catalog. Feel free to contact us with any inquiries.

"Sericite GMS" is a cosmetic ingredient widely used as a functional pigment in makeup products due to its excellent slip and coverage, as well as its smooth texture and soft pearlescent sheen. It is adopted by many manufacturers not only in Japan but also in the United States, Europe, and various Asian countries. Our company has established a consistent manufacturing system from the management of high-quality sericite mining areas to extraction and product development, ensuring a stable supply of high-quality products over many years.
