| 20120007267 | Method of Producing Compostable or Biobased Foams - The present invention describes compostable or biobased foams that are useful for fabricating foamed articles. The foams are produced using a compound comprising a compostable or biobased polyester and a blowing agent. Additives including plasticizers and chain extenders are optionally included in the compostable or biobased composition. These foams can be produced using conventional melt processing techniques, such as single and twin-screw extrusion processes. In one embodiment, foamed strand profiles are cooled and cut using conventional strand pelletizing equipment. In another embodiment, foamed beads are produced by cutting the foamed strand at the face of the extrusion die and the foamed bead or strand is subsequently cooled. The resulting compostable or biobased foamed bead has a specific gravity less than 0.15 g/cm | 01-12-2012 |

| 20120010307 | Expandable Beads of a Compostable or Biobased Thermoplastic Polymer - The invention provides a composition and process for producing expandable beads from a compostable or biobased thermoplastic polymer. A key aspect of this invention is the ability to incorporate sufficient amounts of hydrocarbon blowing agent into the matrix of the compostable or biobased polymer. The following process may be used. First, the raw materials of compostable or biobased polymers, hydrophobic additive, and other additives are mixed by melt processing techniques. Next, a hydrocarbon blowing agent is added to the admixture, either by addition into the melt or by impregnation into the solid, to produce an expandable bead. Small, lightweight, foamed beads are produced by heating the expandable bead. Then, the expanded beads are subsequently used in conventional operations for molding into foamed articles. | 01-12-2012 |
