Abstract

EN UN PROCESO PARA EXTRUSAR UNA ESPUMA DE BAJA DENSIDAD SE SELECCIONA UN ELASTOMERO TERMOPLASTICO ESPUMABLE TAL COMO GOMA TERMOPLASTICA. EL ELASTOMERO TERMOPLASTICO SELECCIONADO SE SUMINISTRA ENTONCES AL INTERIOR DE UN CILINDRO EXTRUSOR CALENTADO EN DONDE SE COMPRIME Y SE FUNDE MEDIANTE LA ACCION DE UN TORNILLO SINFIN. SE INTRODUCE UN AGENTE ESPUMANTE QUE CONSTA DE AGUA EN EL ELASTOMERO TERMOPLASTICO FUNDIDO. EL ELASTOMERO TERMOPLASTICO FUNDIDO Y EL AGUA SE MEZCLAN Y LUEGO SE ENFRIAN HASTA UNA TEMPERATURA PREDETERMINADA, UNIFORME. LA MEZCLA SE EMPUJA ENTONCES A TRAVES DE UN TROQUEL PARA FORMAR UN PERFIL DE ESPUMA EXTRUDIDA.
