Latest Patents

Nakamura's latest patents focus on the process for the preparation of granular stabilizers for chlorine-containing polymers. The first patent describes a granular stabilizer formed by granulating a hardly fusible or infusible powdery stabilizer, combined with a powdery stabilizer aid through an organic solid binder or dispersion medium. This unique formulation ensures that the primary particles are surface-treated with a minimal amount of organic binder, resulting in granules with an average particle size of 0.1 to 2 mm.

The effectiveness of this granular stabilizer is highlighted by its superior dispersibility in chlorine-containing polymers, uniformity of composition, resistance to scattering, good flowability, and blocking resistance. The innovative process significantly reduces the amount of solid binder or dispersion medium required, maintaining excellent performance characteristics.
