Beschreibung
Zusammenfassung:	The expandable filler insert (10) comprises a self-supporting continuous structure (11) having an outer surface which is positioned parallel to the interior shape of a cavity and is spaced apart from the interior surface of the cavity, and spacer and/or fixing element (12) protruding from the self-supporting continuous structure which secures the insert to the interior surface of the cavity. The self-supporting continuous structure comprises polymer matrix containing polymer(s) or polymer precursor and latent blowing agent(s). The expandable filler insert comprises a self-supporting continuous structure having an outer surface which is positioned parallel to the interior shape of a cavity and is spaced apart from the interior surface of the cavity, and spacer and/or fixing element protruding from the self-supporting continuous structure which secures the insert to the interior surface of the cavity. The self-supporting continuous structure comprises polymer matrix containing polymer(s) or polymer precursor and latent blowing agent(s). The latent blowing agent(s) is chosen from chemical blowing agent and/or physical blowing agent. An independent claim is included for the manufacture of expandable filler insert. Formteil mit einem Hauptkörper aus einer reaktiven, vernetzenden, bei einer Temperatur im Bereich von 120 bis 220°C um mindestens 20% expandierbaren Masse, das mindestens ein Befestigungselement und/oder mindestens einen Abstandhalter mit jeweils einer Vorder- und einer Rückseite aufweist, die dadurch definiert sind, dass das gesamte Formteil einschließlich des Befestigungselements oder des Abstandshalters durch zwei parallel ebene Flächen begrenzt ist, wobei die Vorderseite jedes Befestigungselements oder jedes Abstandshalters in der einen der parallelen Flächen und die Rückseite in der anderen der parallelen Flächen liegt. Vorzugsweise wird das Formteil durch Konturextrusion eines Strangs und dessen Zerschneiden hergestellt. Es zeichnet sich durch anisotropes Expansionsverhalten aus. Es wird eingesetzt zur Verstärkung, Dämmung, Dämpfung und/oder Abdichtung von Hohlbauteilen.
