Abstract
Sistema de marcaje de espumas de poliuretano. El sistema consiste en incorporar a la mezcla de los componentes de la espuma aun en fase liquida, es decir, del isocianato y la premezcla de poliol y sus aditivos, inmediatamente antes de la fase de espumación de dicha mezcla, de micropartículas que durante dicha mezcla no entren a formar parte de la estructura molecular de las espumas, dispersándose uniformemente en el seno de la misma y con una coloración diferente de la de dicha espuma, que determina para la misma un aspecto moteado o jaspeado, con cualquier coloración e intensidad. Estas micropartículas pueden ser orgánicas o inorgánicas, rígidas o elásticas, incluso con características de fluorescencia o fosforescencia, pero siempre con un color diferente al de la espuma propiamente dicha.
