Based on a lot of experiments, it shows the distinct error between classical theory curve which express the relation of cell diameter, cell density and foam tensile strength , tensibility tensile product and re-spring degree and experiment curve. It also can＇t explain the relation of hole degree , area of cell wall with above four mechanics parameter. But the sub-cluster scale theory was demonstrated successfully to explain the relation of cell structure and foam mechanics property on different mold temperature, mold pressure, mold period and different chemical blowing agent, blowing activator content.
