Abstract
A method for making rotationally molded objects using resin blends. The resin blend comprises resin pellets and an amount of ground resin powder sufficient to yield rotomolded objects having desirable impact strength and other strength characteristics. Preferably, the resin blend comprises of from about 20% to about 50% by weight of ground resin powder. The resin pellets may optionally contain a reinforcing agent, and such pellets serve as a vehicle for effectively introducing desired reinforcing agents into the product being rotomolded. In addition, resin blends can be used to produce colored objects by rotational molding techniques.
