Abstract

METODO PARA LA FABRICACION DE ARTICULOS CONFORMADOS A PARTIR DE UNA COMPOSICION DE POLIPROPILENO. COMPRENDE LAS OPERACIONES CONSISTENTES EN FUNDIR UNA MEZCLA POLIMERA DE POLIPROPILENO, UN ANTI-OXIDANTE, UN ANTIACIDO, UN PRODEGRADANTE, UN LUBRICANTE Y UN ESTABILIZADOR, FRENTE A LA LUZ; EN MEZCLAR CON LA MASA FUNDIDA POLIMERA RESULTANTE, ANTES DE TRANSFORMARLA EN ARTICULOS CONFORMADOS, HASTA UN 1% EN PESO DE UN ESTER ALQUILICO INFERIOR DE COLOFONIA QUE TIENE UNA VISCOSIDAD GARDNER-HOLT DENTRO DEL INTERVALO DE Y-Z3 A Y-Z4 Y UN INDICE DE ACIDEZ DE APROXIMADAMENTE 6; Y EN CONFORMAR LA COMPOSICION RESULTANTE A LA CONFIGURACION DESEADA. DE APLICACION EN LA FABRICACION DE JERINGUILLAS, TUBERIAS, MATRACES DE CULTIVO DE TEJIDOS, PELICULAS DE EMPAQUETAMIENTO Y SIMILARES.
