Blend of bimodal polyethylene with unimodal ultra high molecular weight polyethylene with improved mechanical properties

摘要

High density polyethylene blend, comprising (A) 55 to 99wt% of a high density multimodal polyethylene component having a density of at least 930 kg/m3, and (B) 1 to 45wt% 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
