It is a lightweight, crack-resistant hollow microparticle of cross-linked polyurethane that has an air layer inside.
Hollow particles with internal space possess lightweight, thermal insulation, and light diffusion properties, and are applied in the fields of electronics and building materials. However, existing hollow particles made from rigid materials such as silica and acrylic resin have faced challenges of being hard and brittle. Negami Industries has utilized its unique polymerization method to apply highly tough and high-strength cross-linked urethane resin to the shell material, thereby improving handling properties while maintaining the unique characteristics of hollow particles.

Company information
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.
