Abstract

Se describe un procedimiento para la producción continua de gránulos en base en polímeros termoplásticos que comprende por lo menos un agente expandible y, opcionalmente, otros polímeros aditivos, entre los cuales los pigmentos inorgánicos y solubles en la matriz polimérica, en donde se prepara una primera corriente principal (21), en el estado fundido, y una segunda corriente (22) en el estado fundido, la cual incluye los aditivos (16) y la cual se agrega a la primera corriente. La mezcla se extruye a través de un troquel (37) el cual se enfría por medio de chorro de agua desde las boquillas colocadas detrás de las cuchillas cortantes.
