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.

Method of forming extruded polystyrene foams and the products made therefrom

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/C, C/Cand C/Cis about 0.25 to about 0.4 said one of C/C, C/Cand C/Chaving a compressive efficiency of at least 70% at a 60% strain, C, Cand Cbeing the compressive strength of the cellular polymer in each of three orthogonal directions E, V and H where one of these directions is the direction of maximum compressive strength in the foam and Cequals the sum of C, Cand C.
