This is a material that microencapsulates latent heat storage substances in a resin shell. - Excellent handling properties; it does not leak even if the latent heat storage substance liquefies! - No aldehyde generation; it is encapsulated with non-melamine resin! - SDGs; it can utilize waste heat, and the latent heat storage substance is derived from biomass. For more details, please refer to the PDF document or feel free to contact us. We have free samples available.

Art Pearl is a spherical cross-linked microparticle polymer produced by aqueous suspension polymerization, which does not aggregate and easily disperses in water and most organic solvents. There are two types of resin: urethane-based and acrylic-based, with particle sizes ranging from 2 to 150 μm. Acrylic-based is used as a light diffuser and matting agent, while urethane-based is used as a tactile modifier and decorative agent. We also offer cross-linked styrene microparticles, cellulose microparticles, and cross-linked urethane acrylate! For more details, please download the catalog. We also provide free samples, online briefings, and product customization. Please feel free to contact us.

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.

It has low oil absorption and excellent stain resistance.
