PROCESS FOR FORMING POLYLACTIDE EXPANDED BEAD FOAM
Expanded poly(lactide) (PLA) beads are made by pressurizing PLA beads with carbon dioxide at approximately room temperature, heating the beads under pressure to 90 to 160C to saturate and partially crystallize the beads, and then depressurizing and cooling the beads. The PLA beads contain a blend of...

| description | Expanded poly(lactide) (PLA) beads are made by pressurizing PLA beads with carbon dioxide at approximately room temperature, heating the beads under pressure to 90 to 160C to saturate and partially crystallize the beads, and then depressurizing and cooling the beads. The PLA beads contain a blend of PLLA and PDLA in certain ratios. The beads are useful for making expanded bead foam.
Las microesferas de poli(láctida) expandidas (PLA) se elaboran presurizando microesferas de PLA con dióxido de carbono a aproximadamente temperatura ambiente, calentando las microesferas a presión a 90 °C a 160 °C para saturar y cristalizar parcialmente las microesferas, y luego despresurizando y enfriando las microesferas. Las microesferas de PLA contienen una mezcla de PLLA y PDLA en ciertas proporciones. Las microesferas son útiles para elaborar espuma expandida de microesferas. |
