Abstract:
Compositions may include a polymer melt blend composition prepared from two polyethylene copolymers having different densities, wherein the polymer melt blend composition possesses improved flowability and impact resistance for low thickness rotomolding applications. Low thickness articles may include a polymer melt blend composition prepared from two polyethylene copolymers having different densities, wherein the articles possess improved finishing properties. Rotomolding processes may include melt blending from two polyethylene copolymers having different densities, pulverizing the melt blend, and rotational molding the composition thereof.
