Abstract

Procedimiento de fabricación de cuerpos huecos transparentes, de tereftalato de polietilonglicol, en el cual se realiza un semielaborado o desbaste que se expansiona a continuación, caracterizado porque partiendo de un desbaste o semielaborado de material caliente, se enfría este desbaste o semielaborado rápidamente a una temperatura inferior o igual a la temperatura de cristalización y próxima a ésta, a continuación de lo cual se provoca rápidamente una expansión del material a un porcentaje suficiente para obtener una biorientación y un enfriado antes de la cristalización substancial del material.
