20080299379 | COMPOSITE MATERIAL AND METHOD OF MAKING THE COMPOSITE MATERIAL - An improved energy absorbing member comprising, an thermoplastic cellular polymer in contact with a structural element such as a metal guard rail or automotive door, wherein the cellular polymer has an average cell size of at least about 0.75 mm and at least one of C | 12-04-2008 |
20090062410 | METHOD OF FORMING EXTRUDED POLYSTYRENE FOAMS AND THE PRODUCTS MADE THEREFROM - The invention a method of forming complex shape of styrenic polymer foams in which a pressing surface is created, for example, by planing/machining a layer of an as formed extruded styrenic polymer plank, contacting said plank with a contoured die face and pressing the foam to form the complex shape. | 03-05-2009 |
20110091688 | PROCESS FOR PRODUCING A SHAPED FOAM ARTICLE - The invention relates to an improved method of cold forming a shaped foam article wherein the improvement is using a near net-shaped foam blank cut from a foam plank having a vertical compressive balance equal to or greater than 0.4 to produce the shaped foam article. | 04-21-2011 |
20110293914 | SHAPED FOAM COMPOSITE ARTICLE - 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. | 12-01-2011 |
20110313072 | METHOD FOR MANUFACTURING A PLURALITY OF SHAPED FOAM ARTICLES - The present invention is a method to manufacture one or more shaped foam article. Specifically, the present invention is a method of extruding a thermoplastic polymer with a blowing agent to form a foam polymer plank having a density gradient. Preferably, shaped articles are prepared from the surface of the foam plank having the lowest density. The article is shaped by a mold comprising one or a plurality of cavities wherein the periphery of each cavity is defined by a trimming rib, said mold concurrently shapes the foam article and trims the resulting shaped foam article from the surrounding continuous unshaped foam plank. Preferably, the foam has a vertical compressive balance (Rv) equal to or greater than 0.4 and more preferably, the foam has a cell gas pressure less than 1 atmosphere and/or an open cell content of equal to or less than 20 percent. | 12-22-2011 |
20120056346 | IMPROVED METHOD FOR EXTRACTING SHAPED FOAM ARTICLES FROM A FORMING MOLD CAVITY - The invention relates to an improved method of extracting a shaped foam article from a mold cavity after being formed, specifically by imparting a vacuum sufficient enough to hold the shaped foam article to one side of the mold, preferably the core half of the mold, when the mold opens. | 03-08-2012 |
20120101174 | METHOD FOR FORMING A SHAPED FOAM ARTICLE - The invention relates to an improved method of cold forming a shaped foam article having a shape with a high degree of draft with improved surface aesthetics, specifically reduced surface cracking and articles made therefrom. The improvement is using a mold with a reduced-slip cavity surface, preferably a textured cavity surface. | 04-26-2012 |
20120114895 | THERMAL INSULATING PANEL COMPOSITE - Prepare an article by providing an extruded thermoplastic polymer foam having a cavity defined therein and placing a vacuum insulation panel entirely within the cavity. | 05-10-2012 |
20120237734 | PROCESS FOR FORMING A DOUBLE-SIDED SHAPED FOAM ARTICLE - The invention relates to an improved method of cold forming a double-sided shaped foam article wherein the improvement is using a double-sided foam blank cut from a foam plank having a vertical compressive balance equal to or greater than 0.4 to produce the double-sided shaped foam article. The double-sided foam blank has a first pressing surface and a second pressing surface wherein the difference in compressive strength between the first and second pressing surfaces is equal to or less than 200 percent, most preferably, the compressive strength of the first pressing surface is the same as the compressive strength of the second pressing surface. | 09-20-2012 |
20130084429 | METHOD FOR STAMPING A SHAPED FOAM ARTICLE - 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. | 04-04-2013 |
