  • Foam cross-linked with metal salt and process for production
    Patent number: 6555591
    Abstract: The present invention has its object to provide a foam outstanding in electrification and heat insulating and sound insulating properties and has high compressive strength even when it has low density. The present invention relates to a foam comprising an organic polymer expanded matrix (I) and at least one kind of inorganic substance (II) selected from the group consisting of metals, metal compounds and non-metal inorganic fillers, wherein said expanded matrix (I) contains metal salt-crosslinks and the relation between the weight percentage (M) of the metal forming said metal salt-crosslinks in the expanded matrix (I) based on the total weight of the expanded matrix (I) and the inorganic substance (II) and the weight percentage (S) of the inorganic substance (II) based on the total weight of the expanded matrix (I) and the inorganic substance (II) satisfies the following expression. M≧10−S/4  (1) wherein M≦50 and S≧5.
