Plastic and elastomer foams may be considered as filled plastic composites, where particles, or cells of gas, are the filler. Produced by injection molding and extrusion, or by pouring in place, these materials are either open or closed cell, or somewhere between the two. In open cell foams the gas cells are interconnected, while in a closed cell foam each cell is totally enclosed by thin plastic walls [1–4].
