发明名称 Moulding composition
摘要 <p>A polyethylene moulding composition having a multimodal molecular weight distribution, having a density according to ISO 1183 at 23�C in the range of 920 to 960 kg/m 3 and an MFR 190/2 according to ISO 1133 in the range of 0.05 to 10 g/10 min, said polyethylene moulding composition comprising at least three ethylene polymer fractions having distinct molecular weights : A) 15 to 50 wt% of a low molecular weight ethylene homopolymer or copolymer fraction with a weight average molecular weight M w in the range of 15 to 40 kg/mol; B) 15 to 50 wt% of a medium molecular weight ethylene homopolymer or copolymer fraction with a weight average molecular weight M w in the range of 70 to 200 kg/mol; and C) 15 to 50 wt% of a high molecular weight ethylene homopolymer or copolymer fraction with a weight average molecular weight M w in the range of 220 to 400 kg/mol, provided that one of A, B and C is an ethylene homopolymer and at least one other component is an ethylene copolymer with at least one C 3 -C 10 comonomer; and wherein the composition has - a Shore D hardness measured according to ASTM D2240-05 (15 sec) of at least 56.0.</p>
