A solid state foamed microcellular foam sheet for use in forming a container is provided. The solid state foamed microcellular foam sheet includes a central foamed section defining a foam layer within the microcellular foam sheet having a first population of cells within which are interspersed a second population of cells.

The invention disclosed herein is an automotive acoustic panel including a porous sound-absorption material made from a polymer and an expanded perlite. One or more silane compounds may be coupled or coated onto the expanded perlite while a coupling agent and a chemical foaming agent may additionally be added to the automotive acoustic panel.

A method includes processing multiple macromolecular staples to successively produce a macromolecular sheet body, multiple silks and multiple sheet particles. The macromolecular sheet body contains multiple district camouflages and is processed by edge cutting to form multiple color strips. The color strips, the silks and the sheet particles are processed and attached to the surface of the macromolecular sheet body, so that the surface of the macromolecular sheet body forms the district camouflages, the thread camouflages and the spot camouflages. Finally, the macromolecular sheet body is vulcanized or solidified in a foam molding zone, to form an elastic mat with a mixed color type.
