ABSTRACT:
A composition useful for rotational molding and method of rotomolding are provided. The composition advantageously includes particulate matter of significantly different sizes. A first polymer is provided as particulate matter of one size, and a second polymer is provided as particulate matter of a smaller size. During rotomolding, the first polymer forms an inner layer and the second polymer forms an outer layer. Beneficially, foaming may be provided during rotomolding to foam the inner layer.
