Se presenta como un s\u00f3lido cristalino blanco e inodoro, con una elevada estabilidad t\u00e9rmica y una excelente compatibilidad con diversos compuestos org\u00e1nicos. Como producto intermedio clave en la industria qu\u00edmica, el NPG se utiliza ampliamente en la producci\u00f3n de resinas, recubrimientos y pl\u00e1sticos debido a su estructura ramificada \u00fanica, que confiere un rendimiento superior a los productos finales.<\/p>\n

Aplicaciones principales<\/h3>\n

Producci\u00f3n de resina de poli\u00e9ster (uso principal):<\/strong> El NPG es un mon\u00f3mero fundamental para la s\u00edntesis de resinas de poli\u00e9ster saturadas y resinas de poli\u00e9ster insaturadas. La estructura ramificada del NPG mejora la estabilidad t\u00e9rmica, la resistencia a la intemperie y la resistencia qu\u00edmica de las resinas, que se utilizan ampliamente en recubrimientos para bobinas, acabados para la automoci\u00f3n y recubrimientos anticorrosivos industriales.<\/p>\n

Recubrimientos en polvo:<\/strong> Es una materia prima fundamental para las formulaciones de recubrimientos en polvo, ya que mejora la fluidez, el brillo y la adherencia de la pel\u00edcula de recubrimiento. Los recubrimientos en polvo a base de NPG son respetuosos con el medio ambiente (sin emisiones de COV) y se utilizan ampliamente en muebles, electrodom\u00e9sticos y herrajes met\u00e1licos.<\/p>\n

Sector del poliuretano (PU):<\/strong> Se utiliza como extensor de cadena en la fabricaci\u00f3n de elast\u00f3meros de poliuretano, espumas y adhesivos, mejorando la resistencia mec\u00e1nica, la elasticidad y la flexibilidad a bajas temperaturas de los productos de poliuretano.<\/p>\n

Lubricantes y plastificantes:<\/strong> Se utiliza como materia prima para la fabricaci\u00f3n de \u00e9steres de neopentilglicol, que son lubricantes de alto rendimiento para motores de autom\u00f3viles y maquinaria industrial, as\u00ed como plastificantes para el PVC con una excelente resistencia al calor.<\/p>\n

Otros usos:<\/strong> Se utiliza en la producci\u00f3n de aditivos para lubricantes sint\u00e9ticos, agentes de apresto textil e intermedios farmac\u00e9uticos.<\/p>","protected":false},"excerpt":{"rendered":"
