Abstract: The present invention relates to a microcellular foam of a thermoplastic resin and a method for preparing the same, and more particularly to a microcellular foam comprising a skin layer having a porosity of below 5% and a core layer having a porosity of at least 5%, wherein the thickness of the skin layer accounts for 5 to 50% of the entire foam, and a method for preparing the same. The microcellular foam of the present invention is advantageous in that it has a thicker skin layer and smaller and uniform micropores in the core layer, compared with conventional microcellular foams, while having mechanical properties comparable to those of conventional non-foamed sheets.
Abstract translation: 本发明涉及热塑性树脂的微孔泡沫及其制备方法，更具体地说，涉及一种微孔泡沫体，其包含孔隙率低于5％的表皮层和具有至少5％孔隙率的芯层， ，其中表层的厚度占整个泡沫的5〜50％，及其制备方法。 本发明的微孔泡沫体的优点在于，与传统的微孔泡沫材料相比，其具有较厚的表层和较细的均匀的微孔，同时具有与常规非发泡片材相当的机械性能。
