  • Publication number: 20220363857
    Abstract: Cellulose ester compositions for expanded foam applications are provided. Specifically, production of melt processed cellulose esters has historically been limited to standard extrusion, molding and solvent casting methods. A combination of cellulose ester formulation and selected blowing agents have been found to produce articles of good density and good dimensional stability for an expanded foam process using conventional polystyrene processing equipment.

  • Publication number: 20200056011
    Abstract: The application discloses cellulose ester compositions comprising two or more miscible blends of cellulose ester each comprising a plurality of propionyl substituents having tunable rheology and physical properties not achievable by any one of the cellulose esters alone. These cellulose ester compositions can be further processed, with or without other materials such as plasticizers, flame retardants, and blowing agents, and converted into articles. These cellulose ester compositions have higher modulus and have low to no butyryl/butyric acid content relative to cellulose acetate butyrate (“CAB”) cellulose ester compositions made from CABs having a butyryl content of greater than 30 wt %.
