Alicyclic carboxylates, such as alicyclic norbonane sodium dicarboxylate, may be used in relatively small amounts as crystallization nucleating agents for foamed polypropylene. The alicyclic carboxylates give improved cell structures at lower proportions than conventional crystallization nucleating agents. The use of alicyclic carboxylate crystallization nucleating agents together with conventional nucleating agents may help give lower density polypropylene foams across a broader melt temperature range.
