Performance super high flow ethylene polymer compositions |
摘要 |
Super high flow ethylene polymer compositions comprising at least one linear ethylene polymer are disclosed which have improved processability for use in making thermally formed articles (e.g., thin-walled lids, cups and containers). The compositions have a processing index from about 0.005 KPoise to about 1 KPoise and are particularly useful in thermal forming processes having shear rates of at least 2,000 sec-1 (e.g., injection molding processes). The compositions can be used to make thin-walled lids and cups and have good environmental stress crack resistance and Gullwing Tear properties.
