Mientras que los POE convencionales y los elast\u00f3meros a base de propileno se dispersan en el PP como una fase de caucho discreta con un desajuste en el \u00edndice de refracci\u00f3n, RX9005 posee una arquitectura molecular con mayor compatibilidad con la matriz de polipropileno. Una mejor compatibilidad de fases es lo que permite que el grado endurezca y reduzca la neblina al mismo tiempo, un resultado que la mayor\u00eda de los modificadores de impacto no pueden ofrecer, porque los dominios que absorben la energ\u00eda de impacto suelen ser los mismos que dispersan la luz.<\/p>\n<p>BASTONE produce RX9005 internamente en su planta de producci\u00f3n de la Zona de Desarrollo Econ\u00f3mico de Hangzhou utilizando una formulaci\u00f3n patentada desarrollada por el centro de I+D del grupo. La densidad mide 0,88 g\/cm\u00b3 seg\u00fan GB\/T 1033.1-2008, y el \u00edndice de fluidez en masa fundida se sit\u00faa entre 2,5 y 3,5 g\/10min seg\u00fan GB\/T 3682-2000 \u2014 una ventana que coincide con las condiciones de cizallamiento de la mayor\u00eda de l\u00edneas de l\u00e1mina de PP y herramientas de moldeo de pared delgada sin reducir el flujo general del compuesto. La resistencia a la tracci\u00f3n en rotura alcanza 17 MPa (GB\/T 1040.2-2006) y el m\u00f3dulo de flexi\u00f3n alcanza 135 MPa (GB\/T 9341-2008).<\/p>\n<p>El m\u00f3dulo de flexi\u00f3n de 135 MPa es el n\u00famero que m\u00e1s importa a los formuladores. Los endurecedores POE est\u00e1ndar se sit\u00faan muy por debajo de esa cifra, por lo que cada punto de mejora en el impacto cuesta rigidez medible en la pieza terminada. Un modificador con mayor m\u00f3dulo inherente permite al formulador mantener el espesor de pared y la rigidez de la pieza mientras a\u00fan gana resistencia al impacto, y el equilibrio rigidez-tenacidad es el conjunto de propiedades para el cual RX9005 fue dise\u00f1ado.<\/p>\n<p>El rendimiento a baja temperatura es la segunda raz\u00f3n por la cual los procesadores especifican este grado. RX9005 proporciona un endurecimiento pronunciado por debajo de la temperatura ambiente y mejora la resistencia al agrietamiento en fr\u00edo en art\u00edculos terminados, relevante para empaques de alimentos refrigerados, contenedores de cadena de fr\u00edo y cualquier pieza de PP transparente que soporte esfuerzos de manipulaci\u00f3n en un ambiente fr\u00edo. La mejora del brillo en superficies moldeadas y extruidas viene como parte del mismo beneficio \u00f3ptico.<\/p>\n<p>Cada lote de producci\u00f3n pasa por el laboratorio de pruebas interno de BASTONE antes de su liberaci\u00f3n, con densidad, \u00edndice de fusi\u00f3n y propiedades mec\u00e1nicas verificadas contra los valores publicados en la hoja de datos t\u00e9cnicos. RX9005 cumple con los requisitos de certificaci\u00f3n de higiene y seguridad de FDA y GB, lo que lo habilita para aplicaciones de envasado en contacto con alimentos y dispositivos m\u00e9dicos donde el estatus regulatorio de un modificador determina si puede utilizarse en absoluto.<\/p>","protected":false},"excerpt":{"rendered":"<p>RX9005 es un modificador de impacto a base de poliolefina fabricado por BASTONE para compuestos de polipropileno transparente, dise\u00f1ado para aumentar la tenacidad sin sacrificar la claridad ni la rigidez.<br \/>\nProducido en la instalaci\u00f3n de BASTONE en Hangzhou bajo cumplimiento de FDA y GB, el grado sirve para extrusi\u00f3n de l\u00e1minas de PP, termoformado, empaques tipo bl\u00edster y moldeo por inyecci\u00f3n de pared delgada.<br \/>\nLa carga recomendada var\u00eda de 3 a 40% dependiendo del equilibrio de propiedades deseado.<\/p>","protected":false},"featured_media":1816,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[62],"product_tag":[],"class_list":["post-1824","product","type-product","status-publish","has-post-thumbnail","product_cat-masterbatch","first","instock","shipping-taxable","product-type-simple"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>RX9005 Toughening Agent for Transparent PP | China Supplier<\/title>\n<meta name=\"description\" content=\"RX-9005 toughening agent for transparent PP: 0.88 g\/cm\u00b3, MFI 2.5\u20133.5 g\/10min, 135 MPa flexural modulus, FDA\/GB food-contact.
