Mohammadreza Nofar, Auteur ; Wenli Zhu, Auteur ; Chul B. Park, Auteur |In this study, the non-isothermal cold crystallization and isothermal melt crystallization of both linear and long-chain-branched (LCB) polylactide (PLA) were investigated using a differential scanning calorimeter (DSC). Talc was used as a nucle[...]

Wentao Zhai, Auteur ; Chul B. Park, Auteur ; Marianna Kontopoulou, Auteur |Currently, the preparation of polypropylene (PP) foam with a well-defined cell structure and a high expansion ratio is receiving increased attention. However, the present technical problems such as poor cell nucleation ability and weak melt stre[...]

Wentao Zhai, Auteur ; Young-Wook Kim, Auteur ; Chul B. Park, Auteur |To investigate the evolution of melting behavior during the steam-chest molding process of expanded polypropylene (EPP) bead, a differential scanning calorimetry (DSC) test involving fast heating, isothermal treatment, and fast cooling was used [...]

Siu N. Leung, Auteur ; Anson Wong, Auteur ; Chul B. Park, Auteur |Two methods to predict the pressure drop threshold (ΔPthreshold) to initiate bubble nucleation in polymer foaming processes are developed. One method uses the modified nucleation theory developed in our previous work, while the other utilizes co[...]
