Bridging acrylic microparticles (polymer microparticles)

It is a spherical microparticle polymer created from suspension polymerization. We have a wide range of products centered around crosslinked polymethyl methacrylate.

- It has a perfect spherical shape with excellent fluidity and smoothness. - It easily disperses in water and most organic solvents. - We offer a range of particles from flexible and elastic to high-strength. - It has excellent heat resistance and solvent resistance. - The average particle size can be adjusted from 2 to 150 μm, with high reproducibility of particle size distribution.

Our company is a chemical enterprise headquartered in Ishikawa Prefecture, engaged in the manufacturing of acrylic resins and urethane acrylates. We have four strengths: (1) Polymerization technology = we possess water-based suspension polymerization, emulsion polymerization, solution polymerization, bulk polymerization, and precipitation polymerization developed over many years, (2) Manufacturing facilities = consistent production from polymerization to washing, drying, and (re-dissolution using flexible batch reactors ranging from 1500 to 6000 liters, (3) Polymer design technology = functionalization of oligomers to high molecular weight substances, introduction of functional groups, and spherical cross-linked microparticle formation, (4) Contract manufacturing = our researchers, who make up 30% of our employees, provide thorough support from laboratory studies to mass production. Products that leverage these four strengths are used in various applications, such as electronic materials, automotive, construction materials, and cosmetics, found in "such things" and "such places" close to you. We are also engaged in the development of polymers using plant-derived raw materials. As a "behind-the-scenes supporter" that enhances our customers' manufacturing competitiveness, we are committed to developing high-value-added products.
