Abstract

Procedimiento para la preparación de un concentrado de agente porógeno a base de un agente porógeno químico y un material sintético termoplástico como material de soporte, caracterizado porque en calidad de material de soporte se utiliza un poliéster y/o copoliéster saturado, con un punto de fusión de cristalitos comprendido entre 100 y 220ºC, preferentemente entre 160 y 200ºC y con una viscosidad reducida de 0,5 dl/g a 1,6 dl/g, preferentemente de 0,7 dl/g a 1,0 dl/g y se incorpora homogéneamente el agente porógeno pasando por la fase de fusión del poliéster o copoliéster, y porque a continuación se desmenuza el concentrado.
