La ruta de producci\u00f3n comienza con propileno de grado polimerizaci\u00f3n como materia prima principal, con etileno introducido como comon\u00f3mero para construir los dominios de fase de caucho responsables del rendimiento al impacto. El hidr\u00f3geno controla el peso molecular. Toda la polimerizaci\u00f3n se lleva a cabo bajo catalizador Ziegler-Natta, seguido de desgasificaci\u00f3n, mezclado y granulaci\u00f3n para producir un producto final limpio y de bajo olor.<\/p>\n<p>PetroChina Lanzhou Petrochemical no es un mezclador de productos b\u00e1sicos: el sitio de Lanzhou alberga una de las instalaciones de PP de mayor capacidad en una sola ubicaci\u00f3n en el noroeste de China. El proceso Spheripol-II proporciona un control estricto de la morfolog\u00eda de las part\u00edculas, lo que se traduce directamente en la consistencia de los gr\u00e1nulos que los compradores ven al llegar: gr\u00e1nulos cil\u00edndricos o redondos planos de color natural, de 2\u20135 mm en cualquier direcci\u00f3n, con un recuento de defectos de part\u00edculas limitado a \u226410 pcs\/kg seg\u00fan SH\/T 1541-2006.<\/p>\n<p>El rango de MFR de 20\u201325 g\/10 min coloca a EP531N firmemente en el segmento de ICP de alto flujo. El moldeo por inyecci\u00f3n automotriz para piezas de gran \u00e1rea \u2014 defensas de parachoques, sustratos de molduras de puertas, soportes de tableros de instrumentos \u2014 exige suficiente fluidez para llenar moldes complejos r\u00e1pidamente sin requerir temperaturas de fusi\u00f3n excesivas. El m\u00f3dulo de flexi\u00f3n m\u00ednimo de 800 MPa proporciona la columna vertebral estructural necesaria para mantener la geometr\u00eda de la pieza bajo carga, mientras que la resistencia al impacto Charpy m\u00ednima de 40 kJ\/m\u00b2 a 23\u00b0C asegura que el material absorba energ\u00eda sin fractura fr\u00e1gil, que es el requisito de rendimiento fundamental para los sistemas de parachoques.<\/p>\n<p>La caracter\u00edstica de bajo olor es un atributo de producci\u00f3n significativo para aplicaciones de interiores. Los componentes de la cabina enfrentan regulaciones de COV cada vez m\u00e1s estrictas en los principales mercados automotrices. Obtener una resina base con bajo olor inherente reduce la carga de aditivos durante la mezcla y simplifica los ciclos de validaci\u00f3n para formulaciones de compuestos aprobadas por OEM.<\/p>\n<p>BASTONE obtiene EP531N directamente de PetroChina Lanzhou Petrochemical a trav\u00e9s de canales de suministro establecidos. Cada env\u00edo est\u00e1 documentado con un Certificado de An\u00e1lisis completo trazable hasta el lote de producci\u00f3n de origen, que cubre todos los cinco par\u00e1metros t\u00e9cnicos enumerados en la norma Q\/SY LS0305-2017. Los compradores reciben COA de f\u00e1brica, no documentos reemitidos, lo cual importa cuando se califica a un proveedor para una auditor\u00eda de la cadena de suministro de un proveedor de nivel 1 o OEM automotriz.<\/p>","protected":false},"excerpt":{"rendered":"<div data-test-render-count=\"1\">\n<div class=\"group\">\n<div class=\"contents\">\n<div class=\"group relative relative pb-3\" data-is-streaming=\"false\">\n<div class=\"font-claude-response relative leading-[1.65rem] [&amp;_pre&gt;div]:bg-bg-000\/50 [&amp;_pre&gt;div]:border-0.5 [&amp;_pre&gt;div]:border-border-400 [&amp;_.ignore-pre-bg&gt;div]:bg-transparent [&amp;_.standard-markdown_:is(p,blockquote,h1,h2,h3,h4,h5,h6)]:pl-2 [&amp;_.standard-markdown_:is(p,blockquote,ul,ol,h1,h2,h3,h4,h5,h6)]:pr-8 [&amp;_.progressive-markdown_:is(p,blockquote,h1,h2,h3,h4,h5,h6)]:pl-2 [&amp;_.progressive-markdown_:is(p,blockquote,ul,ol,h1,h2,h3,h4,h5,h6)]:pr-8\">\n<div class=\"standard-markdown grid-cols-1 grid [&amp;_&gt;_*]:min-w-0 gap-3 standard-markdown\">\n<p style=\"text-align: left;\">PP EP531N is a high-flow impact copolymer polypropylene (ICP) resin produced by PetroChina Lanzhou Petrochemical Company, one of China&#8217;s largest polypropylene manufacturing facilities.<\/p>\n<p style=\"text-align: left;\">With a melt flow rate of 20\u201325 g\/10min and Charpy impact strength exceeding 40 kJ\/m\u00b2, the grade is engineered for automotive exterior and interior components where toughness and processability must be balanced without compromise.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"featured_media":706,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[47],"product_tag":[],"class_list":["post-1097","product","type-product","status-publish","has-post-thumbnail","product_cat-pp","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>PP EP531N Automotive Impact Copolymer | BASTONE<\/title>\n<meta name=\"description\" content=\"PetroChina Lanzhou PP EP531N ICP resin \u2014 MFR 20\u201325 g\/10min, Charpy impact \u226540 kJ\/m\u00b2, flexural modulus \u2265800 MPa.
