HIGH-FLOW FIBER REINFORCED POLYPROPYLENE COMPOSITION |
| 摘要 |
Fiber reinforced composition comprising a heterophasic propylene copolymer, a propylene homopolymer and/or a propylene copolymer, and fibers having an average diameter of 12.0 μm or less, wherein the propylene copolymer comprises not more than 2.0 wt.-% C2 to C10 α-olefins other than propylene, the propylene homopolymer and the propylene copolymer have a melt flow rate MFR2 (230° C.) of at least 100 g/10 min, and the composition has a melt flow rate MFR2 (230° C.) of at least 10 g/10 min |

1. A fiber reinforced composition comprising,
(a) a heterophasic propylene copolymer (HECO), (b) a propylene homopolymer (H-PP1) and/or a propylene copolymer (C-PP1), and (c) fibers (F) having an average diameter of 12.0 μm or less and an aspect ratio of 150 to 450, wherein (i) the propylene copolymer (C-PP1) comprises not more than 2.0 wt.-% C2 to C10 α-olefins other than propylene, (ii) the propylene homopolymer (H-PP1) and the propylene copolymer (C-PP1) have a melt flow rate MFR2 (230° C.) measured according to ISO 1133 of at least 50 g/10 min, and (iii) the fiber reinforced composition has a melt flow rate MFR2 (230° C.) measured according to ISO 1133 of at least 10 g/10 min. |
