Abstract
SE PRESENTA UN PROCESO PARA FABRICAR UNA ESTRUCTURA DE UN POLIMERO AROMATICO ALQUENIL, DE CELULAS CERRADAS, CON UN TAMAÑO DE CELULA AUMENTADO. EN EL PROCESO UN MATERIAL POLIMERO ALQUENIL AROMATICO SE CALIENTA PARA FORMAR UN MATERIAL POLIMERICO FUNDIDO; UN AGENTE DE AUMENTO DEL TAMAÑO DE LAS CELULAS, NO ENCERADO, SE INCORPORA AL MATERIAL POLIMERICO FUNDIDO; UN AGENTE DE SOPLADO SE INCORPORA AL MATERIAL POLIMERICO FUNDIDO A UNA PRESION ELEVADA, PARA FORMAR UN GEL ESPUMABLE, Y EL GEL ESPUMABLE SE EXPANDE DESPUES EN UNA ZONA DE PRESION MAS BAJA, PARA FORMAR LA ESTRUCTURA DE ESPUMA. EL AGENTE DE AUMENTO ESTA PRESENTE EN UNA CANTIDAD SUFICIENTE PARA AUMENTAR EL TAMAÑO DE LA CELULA ESTABILIZADA DE LA ESTRUCTURA DE ESPUMA FABRICADA, EN UN 20 % CON RESPECTO A UNA ESTRUCTURA CORRESPONDIENTE DE ESPUMA ELABORADA SIN EL AGENTE DE AUMENTO. ADEMAS, EL AGENTE DE AUMENTO ESTA INCORPORADO EN CANTIDAD SUFICIENTE PARA QUE LA ESTRUCTURA DE ESPUMA TENGA PROPIEDADES SIMILARES A LA ESTRUCTURA DE ESPUMA CORRESPONDIENTE. TAMBIEN SE PRESENTA LA ESTRUCTURA DE ESPUMA CORRESPONDIENTE AL PROCESO DESCRITO.
