The present application relates to a pumpable thermally foaming filler composition based on a combination of a liquid epoxy resin and a polyvinyl chloride resin and/or acrylic resin powder and at least one alkali metal salt of a fatty acid containing 16 C atoms or 18 C atoms, where the alkali metal is calcium or zinc. These pumpable filler materials provide the advantage that they can swell to provide foams having a high swell value upon wet exposure/storage. A method of filling an enclosed space with a pumpable thermally foaming filler composition and a vehicle component obtainable with the shown method are also described.

    本申请涉及可泵送的热发泡填料组合物,其基于液体环氧树脂和聚氯乙烯树脂和/或丙烯酸树脂粉末和至少一种含有16个C原子或18个C原子的脂肪酸的碱金属盐的组合,其中碱金属是钙或锌。这些可泵送的填料材料提供的优点是它们可以膨胀以在潮湿暴露/储存后提供具有高膨胀率值的泡沫。本发明还描述了用可泵送的热发泡填料组合物填充封闭空间的方法以及用所示方法可获得的车辆部件。
