Abstract:	本研究以兩種不同聚乙烯塑膠粒，經超臨界微細發泡製成之發泡粒進行比較，利用不同溫度及壓力條件下，分別測試其發泡孔徑、外觀色澤等。實驗研究得知，由發泡效果之比較性，得知低密度聚乙烯因其分子結構較高密度聚乙烯脆弱，故其發泡孔徑較為不規則且巨大，而其外觀色澤則不均勻。 In this study, we use the two different polyethylene pellets by the microcellular, to compare foam aperture and appearance color in different temperature and pressure. The results show LDPE's molecule structure is fragile than HDPE's, LDPE foam aperture is more large and irregular, and it is appearance of the color is uneven.
