An Experimental Study of Rotational Molding of Polypropylene/Polyethylene Copolymers

Abstract The objectives of this work are to assess the rotomoldability of rubber toughened polypropylene resins and to investigate how resin properties can influence the process of rotational molding and the final part quality. Four commercially available polypropylene/polyethylene copolymers were tested. The chemical composition and the powder, rheological and thermal properties of the resins were determined. Rotational molding experiments …
