LLDPE SABIC 218BJ
SABIC? LLDPE 218BJ is a butene linear low density polyethylene resin with an additive package typically designed for a broader range of food applications (TNPP free). The good thermal stability allows to use the resin in critical extrusion processing conditions. Films produced from SABIC? LLDPE 218BJ have better draw-down ability compared to lower MFR LLDPE resins. This product is not intended for and must not be used in any pharmaceutical/medical applications.

线性低密度聚乙烯(LLDPE)为无毒、无味、无臭的乳白色颗粒，密度为0.918~0.935g/cm3。它与LDPE相比，具有较高的软化温度和熔融温度，有强度大、韧性好、刚性大、耐热、耐寒性好等优点，还具有良好的耐环境应力开裂性，耐冲击强度、耐撕裂强度等性能，并可耐酸、碱、有机溶剂等而广泛用于工业、农业、医药、卫生和日常生活用品等领域。
应用
LLDPE已渗透到聚乙烯的大多数传统市场，包括薄膜、模塑、管材和电线电缆。防渗漏地膜是新开发LLDPE市场。地膜，一种大型挤出片材，用作废渣填埋和废物池衬垫，防止渗漏或污染周围地区。
LLDPE的一些薄膜市场，例如生产袋子、垃圾袋、弹性包装物、工业用衬套、巾式衬套和购物袋，这些都是利用改进强度和韧性后这种树脂的优点。透明薄膜。抗穿透性和LDPE薄膜的刚度，而不显著影响薄膜的透明度。注塑和滚塑是LLDPE最大的两个模塑应用。这种树脂优越的韧性和低温、冲击强度理论上适于废物箱、玩具和冷藏器具。另外，LLDPE的高抗环境应力开裂性使其适用于注塑与油类食品接触的模塑盖子，滚塑废料容器、燃料箱和化学品槽罐。在管材和电线电缆涂敷层中应用的市场较小，在这里LLDPE提供的高破裂强度和抗环境应力开裂性可满足要求。LLDPE的 65%~ 70%用于制作薄膜。 [1]
聚乙烯(PE)是五大合成树脂之一，聚乙烯主要分为线型低密度聚乙烯(LLDPE)、低密度聚乙烯(LDPE)、高密度聚乙烯(HDPE)三大类。 线型低密度聚乙烯(Linear Low-Density Polyethylene)，英文缩写为LLDPE。线性低密度聚乙烯在结构上不同于一般的低密度聚乙烯。
