IMPROVED METHOD OF FORMING EXTRUDED POLYSTYRENE FOAMS AND THE PRODUCTS MADE THEREFROM

The invention a method of forming complex shape of styrenic polymer foams (10) 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 (10) to form the com...

Zusammenfassung:	The invention a method of forming complex shape of styrenic polymer foams (10) 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 (10) to form the complex shape. Procédé d'obtention de mousses de polymère styrénique de forme complexe consistant à créer une surface de pression, notamment par planage/usinage d'une couche faite d'une planche de polymère styrénique extrudé, à mettre ladite planche en contact avec la face d'une matrice profilée et à comprimer la mousse pour obtenir la forme complexe recherchée.
