Petrothene NA940085 物性表资料
低密度聚乙烯（LDPE）的应用：
LDPE复合挤压广泛作为高阻隔复合层压板的一种组分。重要的要求就是防湿和密封。满足不同的要求，树脂的性能随之不同。它可用于无菌包装、药品与日用品的包装。LDPE主要用途用于薄膜产品（如农业用薄膜，地面覆盖膜，农膜，蔬菜大棚膜，）包装用膜（如糖果，蔬菜，冷冻食品等膜，液体包装用如吹塑薄膜，重包装袋，收缩包装袋，一般工业包装薄膜和食品袋等，还可用于注塑产品；挤塑管材，电线电缆，吹塑中空容器。

NA 940 has been designed for excellent processability, bubble stability and good heat sealing over a wide range of extrusion conditions. Optimum properties are found at melt temperatures of 330°-430°F (165°-221°C) and blow-up ratios between 1.8:1 and 2.5:1. Drawdown to 1.5 mil (38.1 microns) is possible at commercial rates when proper extrusion techniques are used. | ||||||||
