MULTIMODAL POLYPROPYLENE COMPOSITION FOR PIPE APPLICATIONS |
摘要 |
A multimodal propylene copolymer composition suitable for pipe applications comprising a multimodal propylene copolymer (U) with at least one comonomer selected from alpha-olefins with 2 or 4 to 8 carbon atoms in a total amount of 4.0 to 10.0 mole-%, wherein the composition has a melt flow rate MFR 2 (2.16 kg, 230 °C) of 0.05 to 1.00 g/10 min determined according to ISO 1133, a content of xylene cold solubles (XCS) of 4.0 to 17.0 wt.-% determined at 25 °C according to ISO 16152, and a polydispersity index PI of 2.5 to 4.0 Pa -1 determined by rheological measurements according to ISO 6721-1 and ISO 6721-10. |
