Abstract

Compositions que l'on peut mouler en pièces expansées ayant excellentes propriétés. Elle comprend en un mélange intime : a. un polyester linéaire de masse molaire élevée seul ou en combinaison avec un ignifugeant et, décomposable choisi b. un agent d'expansion thermiquement décomposable choisi dans le groupe comprenant essentiellement le carbonate de zinc, le formiate de zinc et leurs mélanges, cet agent étant présent en une quantité au moins suffisante pour provoquer l'expansion de la composition thermoplastique durant le moulage. Application au moulage de pièces expansées.Compositions which can be molded into foamed pieces having excellent properties. It comprises in an intimate mixture: a. a high molecular weight linear polyester alone or in combination with a selected flame retardant and decomposable b. a thermally decomposable blowing agent selected from the group consisting essentially of zinc carbonate, zinc formate and mixtures thereof, this agent being present in an amount at least sufficient to cause the expansion of the thermoplastic composition during molding. Application to the molding of expanded parts.
