Abstract

Método de producción de un material elástico de estructura reticular, consistente en una espuma de látex de caucho cuajada y una espuma de poliuretano también cuajada, presentando cada espuma constitutiva su propia estructura reticular continua individual y las dos estructuras están entremezcladas y coextendidas de manera que formen conjuntamente una masa que ocupa un espacio en común, cubriendo la espuma de látex de caucho la estructura reticular de la espuma de poliuretano, extendiéndose a través de los intersticios de la misma, caracterizado por las operaciones de determinar la dilatación de la composición líquida de látex de caucho en forma de espuma a través de los intersticios de un a espuma de poliuretano cuajada, y cuajar luego la espuma de látex de caucho.
