Abstract:
A polymer blend which comprises:(a) from about 50 wt % to about 80 wt % of a high molecular weight, high density polyethylene that has a density greater than about 0.94 g/cc and an MI2 less than about 0.1 dg/min; and (b) from about 20 wt % to about 50 wt % of a linear low density polyethylene that has a density within the range of about 0.90 to about 0.93 cc/g and an MI2 within the range of about 0.5 to about 5 dg/min, wherein the linear low density polyethylene is a copolymer of ethylene with 1-hexene and the linear low density polyethylene has a dart drop impact strength of greater than about 500 grams as measured by ASTM D 1709/A.
