Disclosed is a foam structure of desirable mechanical strenght made with a low molecular weight alkenyl aromatic polymer material and an inorganic blowing agent. The polymer material has an alkenyl aromatic polymer of a weight average molecular weight of 100,000 to 165,000. The foam structure can be made in processes with reduced pressure drop.
On décrit une structure de mousse de résistance mécanique désirée, obtenue à l'aide d'un matériau polymère aromatique alcényle de faible masse moléculaire et d'un agent gonflant inorganique. La moyenne de la masse moléculaire du polymère aromatique alcényle est comprise entre 100 000 et 165 000. La structure de mousse peut être fabriquée à l'aide de procédés à faible chute de pression.
