Expandable filler insert for filling hollow spaces, comprises self-supporting continuous structure including polymer matrix containing polymer(s) or polymer precursor and latent blowing agent(s), and spacer and/or fixing element

摘要

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.
