[New Product] Hollow Urethane Microparticles ART PEARL H-600T
We have developed a manufacturing technology based on cross-linked polyurethane microparticles and started market deployment in May under the product name ART PEARL H-600T. Our company utilizes a unique polymerization method to apply high toughness and high strength cross-linked polyurethane resin to the shell material, enhancing the handling properties while maintaining the unique characteristics of hollow particles (lightweight, thermal insulation, light diffusion). We have prepared free samples. Please feel free to contact us.

Ceramic binder: methacrylic resin
This is a methacrylic resin suitable for ceramic binders. Since it is manufactured using our specialty "water-based suspension polymerization," it results in a polymer with minimal impurities. Please download the catalog to check the material properties. We also conduct product presentations online and can accommodate prototype and mass production according to customer needs.
About根上工業
Our products are used in "things like that" and "places like those" that are right next to you.
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.
