Abstract

La présente invention concerne un matériau d'amortissement pouvant être utilisé dans une automobile, des meubles et analogues, comprenant un produit moulé expansé dans lequel est incorporé un composant actif qui permet d'augmenter le moment dipolaire dudit produit expansé, la quantité dudit composant actif étant comprise entre 10 et 200 parties en poids pour 100 parties en poids de produit expansé. Le matériau d'amortissement ne présente pas seulement une faible résilience de rebondissement, mais également une dureté considérable, ce qui lui donne de bonnes propriétés d'amortissement. Le matériau d'amortissement possède une structure expansée résistante à la destruction même lors de la déformation et présente de bonnes caractéristiques de retour à la forme initiale après déformation.
