Polymer Blends With Improved Processability For TPO Roofing Membranes and Methods For Making Same
A polymer blend includes 35 to 50 wt % of at least one propylene-based elastomer, 25 to 50 wt % of at least one impact copolymer; and 15 to 25 wt % of at least one low density polyethylene component. The propylene-based elastomer has a heat of fusion less than about 80 J/g, greater than 50 wt % propylene and from about 3 wt % to about 25 wt % units derived from one or more C2 or C4-C12 α-olefins, based on a total weight of the propylene-based elastomer. The low density polyethylene has a density of about 0.90 g/cm3 to about 0.94 g/cm3. The polymer blend is useful for making a roofing membrane.
