摘要： The present invention is a method to manufacture shaped foam composite articles comprising a foam core and one or more skin and shaped foam composite articles made therefrom. Specifically, cold formed shaped foam articles having an upper and lower surface having a skin applied to one or both of the surfaces. Preferably the foam comprises a styrenic polymer foam and the skins may independently be mono-layered or multi-layered. The shaped foam article and the skin may be made from the same or different materials. In the case where there are more than one skin, the skins may comprise the same or different materials.

摘要： Prepare extruded thermoplastic polymer foam by preparing a foamable polymer mixture containing thermoplastic polymer and blowing agent at a mixing pressure, cooling the foamable polymer mixture and extruding it through a foaming die at a die pressure at least 90 bars lower than the mixing pressure and out through a die opening having cross sectional dimensions of 2.5 millimeter or more and a cross sectional area of at least 700 square millimeters at a flow rate greater than 500 kilograms per hour and allow it to expand into a polymer foam between shaping elements while restraining the extrusion rate with a restraining device so as to form polymer foam having 96 volume percent or less void volume, anisotropic cell size, a thickness of 50 millimeter or greater, compressive and tensile moduli in the thickness dimension greater than 35 mega pascals and an average shear modulus greater than 16 mega pascals.

摘要： The invention relates to an improved method of cold forming a shaped foam article from a foam having a vertical compressive balance equal to or greater than 0.4 and one or more pressing surface and articles thereof. The improvement comprises the use of a stamping press to form the shaped foam article. Preferably, the stamping press is operated by mechanical or hydraulic means. The shaped foam article may be shaped on one or more surfaces.
