Abstract
SE PRESENTA UN PROCESO PARA FABRICAR UNA ESPUMA DE POLIURETANO FLEXIBLE, EMPLEANDO UN COMPUESTO SURFACTANTE DE SILICONA QUE CONTIENE ENTRE 5 Y 20% DE UN SURFACTANTE DE SILICONA DE UN BAJO PESO MOLECULAR DEFINIDO Y ENTRE EL 95 Y 80% DE UN SURFACTANTE DE SILICONA DE UN ALTO PESO MOLECULAR DEFINIDO. EL USO DE LA MEZCLA PROPUESTA DE SURFACTANTES SUMINISTRA ESPUMAS QUE TIENEN UNA INSPIRABILIDAD MEJORADA CON RELACION A OTRAS ESPUMAS PRODUCIDAS USANDO SOLAMENTE SURFACTANTES DE SILICONA DE ALTO PESO MOLECULAR.
