Title
(EN) IMPROVED METHOD OF FORMING EXTRUDED POLYSTYRENE FOAMS AND THE PRODUCTS MADE THEREFORM
(FR) PROCÉDÉ AMÉLIORE DE FORMATION DE MOUSSES DE POLYSTYRÈNE EXTRUDÉ ET PRODUITS AINSI OBTENUS
Abstract
(EN)
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.
(FR)
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.
