摘要
High density polyethylene blend, comprising (A) 55 to 99 wt% of a high density multimodal polyethylene component having a density of at least 930 kg/m3, and (B) 1 to 45 wt% of an ultra-high molecular weight polyethylene homo- or copolymer component having (i) an intrinsic viscosity of at least 15.0 dl/g (ii) an a nominal viscosity molecular weight (Mv) of at least 2.0*10 6 g/mol and (iii) a molecular weight of (M w ) of at least 0.7*10 6 g/mol, and wherein said blend has an MFR 21 of 0.05 to 10.0 g/10min and a density of at least 925 kg/m3.
