Abstract
A method for making foamed thermoplastic materials includes processing a composition that contains (a) at least one thermoplastic material selected from one or more polyhydroxyalkanoates (PHAs), poly(lactic acid) (PLA), or combinations thereof; and (b) at least one organic peroxide under conditions effective to permit the composition to foam. The foamed thermoplastic materials provide a low density and lightness in weight, can be used in a variety of useful articles spanning many industries, and can have, depending on the choice of thermoplastic materials, excellent biodegradability compared to foamed polymers derived from non-renewable resources.
