En lugar de actuar como clarificador, NA-65H funciona como un nucleador alfa de tipo rigidez: siembra la formaci\u00f3n de cristales durante el enfriamiento para que el pol\u00edmero forme una poblaci\u00f3n m\u00e1s grande de esferulitas m\u00e1s peque\u00f1as y de tama\u00f1o m\u00e1s uniforme. El refinamiento de cristales es el mecanismo detr\u00e1s de cada mejora de propiedad downstream que entrega el aditivo.<\/p>\n<p>Los datos de rendimiento de las pruebas comparativas propias de BASTONE muestran lo que aporta el refinamiento. Con una carga de 0,1%, NA-65H eleva el m\u00f3dulo de flexi\u00f3n al rango de 1900+ MPa y la resistencia a la flexi\u00f3n por encima de 50 MPa, igualando o superando al NA-11 importado probado con la misma carga en la misma matriz de PP. La temperatura de cristalizaci\u00f3n (Tc) supera los 128 \u00b0C con 0,1% de NA-65H, de nuevo por delante de la referencia importada a 128 \u00b0C o menos.<\/p>\n<p>Una Tc m\u00e1s alta importa m\u00e1s en el piso de moldeo que en el laboratorio. Cuando el PP comienza a cristalizar a una temperatura m\u00e1s alta, la pieza se asienta antes en la fase de enfriamiento, lo que acorta el tiempo de ciclo y aumenta el rendimiento en prensas de inyecci\u00f3n y l\u00edneas de peletizado por extrusi\u00f3n por igual. Los moldeadores que operan herramientas de alta cavidad para tapas y cierres sienten el efecto de inmediato en piezas por hora.<\/p>\n<p>Las ganancias en rigidez y resistencia al calor abren el segundo conjunto de aplicaciones. Un mayor m\u00f3dulo de flexi\u00f3n y una mayor temperatura de distorsi\u00f3n por calor permiten a los compounders mantener el rendimiento de la pieza mientras adelgazan las secciones de pared o reducen la carga de relleno, \u00fatil en PP modificado automotriz y en piezas de electrodom\u00e9sticos que soportan carga t\u00e9rmica sostenida. NA-65H tambi\u00e9n mejora la transparencia y el brillo superficial, y no migra ni florece a la superficie, lo que respalda aplicaciones de contacto con alimentos.<\/p>\n<p>BASTONE fabrica NA-65H internamente en su instalaci\u00f3n de la Zona de Desarrollo Econ\u00f3mico de Hangzhou utilizando su propia formulaci\u00f3n y proceso. La producci\u00f3n se encuentra dentro de un grupo qu\u00edmico orientado a I+D con 4 sitios de producci\u00f3n y 1 centro de I+D, por lo que la consistencia lote a lote se controla en origen en lugar de verificarse despu\u00e9s de la compra. El laboratorio de BASTONE realiza las mismas pruebas de flexi\u00f3n y de cristalizaci\u00f3n por DSC mostradas anteriormente sobre el material de producci\u00f3n, y los compradores reciben los resultados con cada env\u00edo.<\/p>","protected":false},"excerpt":{"rendered":"<p>NA-65H es un agente nucleante alfa que mejora la rigidez para polipropileno, fabricado por BASTONE en su instalaci\u00f3n de producci\u00f3n en Hangzhou.<br \/>\nEl aditivo induce cristalizaci\u00f3n orientada en PP, refinando el tama\u00f1o de los cristales y reduciendo la distribuci\u00f3n de tama\u00f1os para elevar el m\u00f3dulo de flexi\u00f3n, la resistencia al calor y la velocidad de cristalizaci\u00f3n.<br \/>\nLos compounders lo utilizan en extrusi\u00f3n, moldeo por inyecci\u00f3n y moldeo por compresi\u00f3n para carcasas de electrodom\u00e9sticos, PP modificado automotriz, componentes el\u00e9ctricos y cierres.<\/p>","protected":false},"featured_media":1808,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[62],"product_tag":[],"class_list":["post-1822","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>NA-65H Nucleating Agent for Polypropylene | China Supplier<\/title>\n<meta name=\"description\" content=\"NA-65H \u03b1-nucleating agent for PP: 0.05\u20130.3% loading, 1,900\u20131,950 MPa flexural modulus, Tc 128 \u00b0C, non-migrating for food-contact caps.
