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.
