Abstract
PARA LA ELABORACION DE EXTRUDADOS, COMO PERFILES O GRANULADOS, SE ELABORA EL POLIETILENO DEL PESO MOLECULAR ULTRA ALTO EN FORMA DE POLVO O DE PIEZAS PEQUEÑAS EN UN DISPOSITIVO DE EXTRUSION DE TORNILLO SINFIN. MEDIANTE LA UTILIZACION DE UNA GEOMETRIA DETERMINADA DEL TORNILLO SINFIN SE EVITA EL DESMONTAJE TERMICO DEL POLIMERIZADO EN SUS PRODUCTOS DE PESO MOLECULAR BAJO. A TRAVES DE ELLO SE OBTIENE EL PERFIL CON UNA SUPERFICIE IMPECABLE, QUE ESTA LIBRE DE RECHUPES Y POROS Y NO MUESTRA NINGUNA TENSION INTERNA.
