Abstract
EN UN PROCEDIMIENTO Y UN DISPOSITIVO DE EXTRUSION PARA LA PRODUCCION DE UN POLIMERO ESPUMOSO, SE FUNDE UN POLIMERO CONDUCIDO, AÑADIENDOSE AL CALDO DE FUSION POLIMERO UN AGENTE ESPUMOSO. UNA VEZ MEZCLADO EL CALDO DE FUSION POLIMERO Y EL AGENTE ESPUMOSO, SE GENERA EN UN ESTRANGULADOR UNA CAIDA DE PRESION CON EL FIN DE FORMAR GERMENES PARA BURBUJITAS DE GAS O CELULAS. A CONTINUACION SE MOLDEA, ESPUMEA Y REFRIGERA LA MEZCLA DE CALDO DE FUSION POLIMERO Y AGENTE ESPUMOSO. PARA PRODUCIR CONTINUAMENTE POLIMERO ESPUMOSO CON ESTRUCTURA MICROCELULAR O SUBMICROCELULAR DE BUENA CALIDAD Y SIN LIMITACIONES DURANTE EL MOLDEO, EL ESTRANGULADOR MUESTRA, PARA CONTROLAR LA CANTIDAD DE FLUIDO EN CIRCULACION, UN MANDO DE PASO, DE MANERA QUE PUEDE AJUSTARSE LA CANTIDAD DE FLUIDO EN CIRCULACION INDEPENDIENTEMENTE DE LA CAIDA DE LA PRESION.
