POLYMER COMPOSITION FOR BUMPERS AND INTERIORS AND POLYETHYLENE-BASED RESIN PRECURSOR |
摘要 |
Polyolefin compositions suitable for injection molded items e.g. for impact bumpers and car interiors comprising from 30% to 90% by weight of an heterophasic propylene polymer composition (A) ; and from 10% to 70% by weight of a multimodal ethylene/butene-1 copolymer (B); having density from 0.850 to 0.935 g/cm 3 , total comonomer content from 6% to 30% by weight, Mw/Mn from 4 to 20; intrinsic viscosity in decalin at 135°C from 1.0 to 4.0 dL/g, and comprising an HDPE fraction (HDPE %wt) up to 30%wt; further comprising from 0 to 50 % by weight of a filler (C) and optionally, in amount up to 10% by weight with respect to the overall composition, an impact modifier masterbatch component D consisting of an ultra-soft heterophasic copolymer component. |
