Abstract

PROCEDIMIENTO PARA LA FABRICACIÓN DE POLIPROPILENO HUMECTADO Y EN SU CASO ESPUMADO, caracterizado por cuanto, inicialmente se procederá a elaborar una mezcla homogénea de polipropileno con contenido aproximado del 2 al 20% en peso, respecto al peso del polipropileno, de polibutadieno con un peso molecular aproximadamente de 500 a 10.000 y dado el caso con los adecuados medios humectantes y/o espumógenos los que se realizará a temperaturas inferiores a las de descomposición de los medios humectantes o espumógenos, conformando, dado el caso, la mezcla adecuadamente, mezcla que será tratada con radiaciones energéticas con dosis comprendidas aproximadamente entre los 2 y 20 Mrad. y/o calentada en un horno para conseguir su humectación, y en su caso, la correspondiente espumación.
