It is a microparticle polymer of urethane that has a soft and moist texture, created from suspension polymerization.
- It is a spherical cross-linked fine particle with excellent fluidity and slip properties. - It easily disperses in water and most organic solvents. - It has excellent heat resistance and solvent resistance.
It is a cross-linked polyurethane microparticle with excellent flexibility. It contributes to stress relief in rigid resins.
Dynamic beads are urethane microparticles synthesized through a suspension polymerization reaction. They are spherical in shape with a particle diameter on the order of micrometers, and it is possible to adjust their composition, hardness, and particle size. 【Features】 - High flexibility and resilience of urethane - Sharp particle size distribution - Stress relaxation in rigid resins, low warping, and prevention of cracking during processing - Excellent dispersibility in various organic solvents - High heat resistance and humidity reliability due to cross-linked microparticles - Light diffusion properties - Matte finish
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.
It is a polyurethane-based microparticle with hardness equivalent to glass beads!
It has low oil absorption and excellent stain resistance.
It is a spherical microparticle polymer with a biomass content of 94%.
- The glass transition temperature is low at -38°C, and it has soft fine particles. - The decomposition starting temperature is high at 335°C, indicating good heat resistance.
