Abstract

UN PROCESO PARA FORMAR UN ARTICULO ESPUMADO QUE TIENE UNA ESTRUCTURA DE CELULA CERRADA SIN NECESIDAD DE UTILIZAR UN AGENTE DE SOPLADO HALOGENADO. EN EL PROCESO, SE SUMINISTRAN UNA MEZCLA DE POLIMERO QUE COMPRENDE AL MENOS EL 50% EN PESO DE UN POLIMERO ESTIRENICO Y HASTA EL 50% EN PESO DE UN POLIMERO ACRILICO QUE TIENE UN PESO MOLECULAR MEDIO QUE ES INFERIOR AL 90% DEL PESO DEL POLIMERO ESTIRENICO Y UN AGENTE DE SOPLADO DE HIDROCARBURO, A UN EXTRUSOR CALIENTE DONDE LA MEZCLA SE FORMA Y EL AGENTE DE SOPLADO INCORPORADO PARA FORMAR UNA MEZCLA FUNDIDA DESDE LA CUAL EL ARTICULO ESPUMADO SE FORMA AL LIBERAR DEL EXTRUSOR.
