Title: Atsushi Nanasawa: Innovator in Flame Retardant Compositions
Introduction
Atsushi Nanasawa is a notable inventor based in Sodegaura, Japan. He has made significant contributions to the field of flame retardant materials, holding a total of 3 patents. His work focuses on developing compositions that enhance safety and performance in various applications.
Latest Patents
Nanasawa's latest patents include a flame retardant composition and a phosphazene composition. The flame retardant composition comprises a polyphenylene ether resin with a number average molecular weight in terms of polystyrene ranging from 500 to 5,000, combined with a phosphazene compound. The content of the polyphenylene ether is between 20 to 95% by weight, while the phosphazene compound constitutes 80 to 5% by weight. This innovative composition is noted for its excellent processability when added to resins, providing a halogen-free resin composition that balances processability, heat resistance, and flame retardancy. The phosphazene composition, on the other hand, has a volatile component content of not less than 0.02% by weight and not more than 1.0% by weight when heated at 200°C for 2 hours. It exhibits excellent resistance to hydrolysis and, when added to a resin, maintains a balance of resistance to hydrolysis, flame retardancy, and stability of electric characteristics in high-frequency fields of not less than 1 GHz.
