Patent

CA 2740142

The present invention relates to a particulate, expandable polymer, for example polystyrene (EPS) or polylactic acid (PLA) or a combination thereof, which can be processed to form a foam having a fine cell structure and a low density, and which contains a thermal insulation value-increasing material so as to increase the thermal insulation value thereof The present invention further relates to a method for producing such particulate, expandable polymer, as well as to a foam material based on such a polymer.

Cette invention concerne un polymère particulaire expansible, par exemple, polystyrène (EPS) ou acide polylactique (PLA) ou une combinaison de ceux-ci, qui peut être converti en une mousse ayant une structure alvéolaire fine et une basse densité, et qui contient un matériau d'isolation thermique à valeur ajoutée de manière à accroître sa valeur d'isolation thermique. Cette invention concerne également un procédé de production dudit polymère particulaire expansible, ainsi qu'un matériau de mousse à base dudit polymère.
