By using the microcellular foamed polymer, the manufacturing cost is decreased cause of its micro void fractions. Also, the reduction of mechanical property is smaller than conventional polymer foaming process. Refer to the previous research, the cell morphology of microcellular foamed polymer is showing the new properties (reflection, thermal insulation, permittivity and etc…). This study is to know the cell morphology of microcellular foamed polymer by using external force. To know the different of applied the external force for polymer crystallinity, we used the XRD. Also, to view the cell morphology, we used the SEM.
