Polyethylene pipe resins |
| abstract |
A polyethylene resin comprising from 44 to 55 wt % of a high molecular weight polyethylene fraction, and from 45 to 56 wt % of a low molecular weight polyethylene fraction; the high molecular weight polyethylene fraction comprising a linear low density polyethylene having a density of from 0.913 to 0.923 g/cm 3 , and an HLMI of from 0.02 to 0.2 g/10 min; and the low molecular weight polyethylene fraction comprising a high density polyethylene having a density of at least 0.969 g/cm 3 and an MI 2 of greater than 100 g/10 min; wherein the relationship between the density D of the resin in g/cm 3 and the weight fraction of the low molecular weight fraction P 1 is defined by 0.055P 1 +0.916<D<0.034P 1 +0.937. |
