HIGH FLOW POLYOLEFIN COMPOSITION WITH LOW SHRINKAGE AND CLTE |
摘要 |
Polyolefin composition comprising
(a) a heterophasic propylene copolymer comprising a polypropylene (PP) having a melt flow rate MFR 2 (230 °C) of 30 to 350 g/10min, and an elastomeric propylene copolymer (E) having an intrinsic viscosity (IV) in the range of 1.5 to 3.0 dl/g and
(b) a polyethylene having a melt flow rate MFR 2 (190 °C) of 15 to 100 g/10min, wherein
(i) the total polyolefin composition has a melt flow rate MFR 2 (230 °C) of more than 15 to 200 g/10min, and
(ii) the weight ratio of elastomeric propylene copolymer to the polyethylene is below 2.0. |
