摘要

The present invention relates to a filler material-containing isocyanate-based elastomer wherein the filler material is present at a level of from about 30% to about 90% by weight of the elastomer and has a specific gravity of less than about 2.0. The present invention also provides a method of making a catalyst, comprising: providing a first mixture comprising a catalyst and a substantially inert fill material wetted by a catalyst; Providing a second mixture comprising an isocyanate and an active hydrogen-containing compound, wherein the isocyanate and the active hydrogen-containing compound are in substantially unreacted state; Providing a reaction mixture by mixing the first mixture and the second mixture; And reacting the reaction mixture to prepare an isocyanate-based elastomer. The present invention also relates to a method for producing an isocyanate-based elastomer.
