Abstract:
A molded thermoplastic article including a hollow body is provided, the article comprising a first layer, and a foamed second layer, the first layer and foamed second layer defining a wall structure, the foamed second layer having a lighter density relative to the first layer. In the wall structure, the ratio of the first layer to foamed second layer varies along the length of the article.
