Abstract

La presente invención se refiere a un metodo para hacer material de filtración espumado, en donde un material plástico en partículas, un polisacárido y agua son alimentados a un extrusor, el extrusor siendo operado bajo condiciones de temperatura y presión tales que a la salida del extrudado del dado de extrusión, el extrudado asuma una sección transversal mayor que aquella en el orificio de salida del dado del extrusor.The present invention relates to a method of making foamed filter material, wherein a particulate plastic material, a polysaccharide, and water are fed to an extruder, the extruder being operated under conditions of temperature and pressure such that at the extrudate exit of the extrusion die, the extrudate assumes a larger cross section than that in the exit hole of the extruder die.
