  • Patent number: 11905407
    Abstract: Polylactide (PLA) parts can be crystallized via two procedures. In the first procedure, i.e. a 2-step post-mold annealing process, the complete crystallization of PLA parts can be done after molding in a secondary operation called as post-mold annealing to make higher heat-resistant PLA parts. There are limitations to this 2-step operation, namely, a) warpage of parts with complex geometries, and b) scaling up higher production volume times. In the second procedure, i.e. 1-step in-mold annealing process, the complete crystallization of PLA parts can be done in the mold itself by holding the temperature of the mold at the crystallization temperature of PLA which is about 100° C. The 1-step in-mold annealing process using a masterbatch blended with neat PLA results in a highly crystalline article produced in a significantly lower cycle time.
