Abstract

SE HA DESCUBIERTO QUE UNA PELICULA DE ESPUMA DE POLIESTIRENO QUE CONTENGA UNA RESINA DE POLIESTIRENO QUE INCLUYA DE UN 1 A UN 15% EN PESO DE UN COMPONENTE DE CAUCHO EN EL QUE LA MAYORIA DE LAS PARTICULAS TENGAN UN TAMAÑO INFERIOR A 0,45 MICRAS APROXIMADAMENTE, ES EXCELENTE PARA LA FORMACION DE ARTICULOS POR EMBUTIDO PROFUNDO. OPCIONALMENTE SE PUEDEN REVESTIR O LAMINAR POR EXTRUSION UNA O DOS PELICULAS A LA HOJA DE ESPUMA ANTES DE LA TERMOFORMACION. TAMBIEN SE PRESENTA UN METODO PARA LA TERMOFORMACION DE UNA HOJA DE ESPUMA. SE PRECALIENTA LA HOJA, SE SUJETA LA HOJA ENTRE LOS MIEMBROS DEL MOLDE MACHO (10) Y HEMBRA (50) COINCIDENTES, SE MUEVEN LOS MIEMBROS A LA POSICION FINAL AL TIEMPO QUE SE APLICA UN VACIO A TRAVES DE LOS DOS MIEMBROS A AMBOS LADOS DE LA HOJA DE ESPUMA Y A CONTINUACION SE REFRIGERA LA ESPUMA FORMADA PARA DARLE LA FORMA FINAL.
