Abstract
MODIFICACIONES POLIMERICAS PARA APLICACIONES DE TERMOCONFORMADO. MODIFICACIONES POLIMERICAS PARA APLICACIONES DE TERMOCONFORMADO EN EQUIPOS CONVENCIONALES, ENTENDIENDO POR TALES, AQUELLOS QUE NO HAN SIDO DISEÑADOS O MODIFICADOS ESPECIALMENTE PARA TERMOCONFORMAR POLIPROPILENO, EN LAS QUE EL POLIMERO QUE SE MODIFICA ES POLIPROPILENO HOMOPOLIMERO ISOTACTICO Y EL POLIMERO MODIFICADOR ES POLIETILENO DE ALTA DENSIDAD, ENTENDIENDO POR TAL, HOMOPOLIMEROS DE ETILENO Y COPOLIMEROS DE ETILENO Y ALFA-OLEFINAS DE DENSIDAD IGUAL O SUPERIOR A 0,935 GR/CM3. EL POLIMERO MODIFICADOR TIENE UN INDICE DE FLUIDEZ, MEDIDO SEGUN LA NORMA ISO-1133, A 190 C Y 21,6 KG INFERIOR A 50 GR/MIN. Y EN UNA PROPORCION ENTRE 5 Y 25% EN PESO. ESTA MODIFICACION PUEDE HACERSE MEDIANTE MEZCLA EN FUNDIDO DE AMBOS COMPONENTES EN EQUIPOS DE MEZCLA DE POLIMEROS QUE GENERAN ALTO ESFUERZO DE CIZALLA, COMO RODILLOS MEZCLADORES, MEZCLADORES INTERNOS, EXTRUSORAS DE DOBLE HUSILLO, ETC., TODOS ELLOS BIEN CONOCIDOS Y MUY UTILIZADOS EN LA INDUSTRIA DE POLIMEROS TERMOPLASTICOS. EL POLIPROPILENO ASI MODIFICADO TIENE PROPIEDADES SUSTANCIALMENTE IGUALES AL POLIPROPILENO SIN MODIFICAR, PRESENTANDO LA CARACTERISTICA DE QUE PUEDE SER MOLDEADO EN EQUIPOS DE TERMOCONFORMADO CONVENCIONALES EN UN AMPLIO INTERVALO DE CONDICIONES DE PROCESO Y OPERANDO EN CONTINUO, LO QUE NO ES POSIBLE CON EL POLIPROPILENO SIN MODIFICAR.
