  • Foamable compositions for rotational molding
    Patent number: 5928584
    Abstract: Novel molding compositions consisting essentially of a mixture of a skin-forming component and a foam core-foaming component physically dry-blended together. The skin-forming component comprises two distinct phases blended together, a high zero-shear viscosity material and a low zero-shear viscosity material. The foam core-forming component preferably comprises a foamable polymeric material including a suitable blowing agent. In a preferred embodiment, the three materials are selected from suitable homopolymers and copolymers of ethylene.
