Organic infrared attenuation agents
Last updated:
Abstract:
Organic infrared attenuation agents have been developed to improve the thermal insulation properties of polymeric foams such as polystyrene low density foams. The organic infrared attenuation agents can include polyols such as sorbitol, maltitol, and poly(ethylene glycol), polysaccharides such as starch or cellulose, and infrared attenuation polyesters such as polybutylene terephthalate. The organic attenuation agents include aromatic compounds or carbon oxygen bonds that are effective in absorbing infrared radiation at the desired wavelengths.
