Abstract

UNA COMPOSICION DE POLIMERO TERMOPLASTICO QUE INCORPORA AL MENOS APROXIMADAMENTE UN 50% EN PESO DE POLIPROPILENO, AL MENOS APROXIMADAMENTE UN 20 % EN PESO DE UN ELASTOMERO TAL COMO CAUCHO EP Y AL MENOS APROXIMADAMENTE UN 4 % EN PESO DE PLASTOMERO. EL PLASTOMERO ES PREFERENTEMENTE UN COPOLIMERO BASADO EN ETILENO CATALIZADO EN UN CENTRO QUE TIENE UNA DENSIDAD INFERIOR A APROXIMADAMENTE 0,915 G/CM{SUP,3}. EL AJUSTE DE LA CANTIDAD DE PLASTOMERO EN LA COMPOSICION PERMITE UN CONTROL CONSIDERABLE SOBRE LA CONTRACCION POSTMOLDEO DE LOS COMPONENTES PRODUCIDOS MEDIANTE LAS OPERACIONES DE MOLDEO POR INYECCION QUE UTILIZA LA COMPOSICION. LA COMPOSICION PUEDE PREPARARSE COMO UNA MEZCLA DE REACTOR O DE FUSION. LA COMPOSICION ES PARTICULARMENTE UTIL PARA LA PRODUCCION DE COMPONENTES TALES COMO PARACHOQUES Y ELEMENTOS EXTERIORES PARA AUTOMOVILES.
