Abstract:
A polymer blend which comprises:(a) from about 20 wt % to about 80 wt % of a high molecular weight, medium density polyethylene that has a density within the range of about 0.92 to about 0.944 g/cc, an MI2 within the range of about 0.01 to about 0.5 dg/min, an MFR within the range of about 50 to about 300, and a multimodal molecular weight distribution comprising a low molecular weight component and a high molecular weight component wherein the low molecular weight component has an MI2 from about 50 to about 600 dg/min and a density from about 0.94 to about 0.97 g/cc; and (b) from about 20 wt % to about 80 wt % of a linear low density polyethylene that has a density within the range of about 0.90 to about 0.925 cc/g and an MI2 within the range of about 0.5 to about 50 dg/min.
