La energía eólica es la fuente de energía de mayor crecimiento en el mundo, este tipo de energía aporta a la industria y las empresas electricidad limpia y renovable. Hoy en día, el diseño de los aerogeneradores y las turbinas de los molinos se está volviendo cada vez más complejo y sofisticado, para poder construir parques eólicos que puedan operar en condiciones altamente exigentes en lugares en alta mar y en climas fríos y / o cálidos. Huntsman Advanced Materials es un apasionado de mejorar la calidad de vida de las personas en todo el mundo. Desde hace más de una década, la compañía se centró en apoyar la cadena de valor de la energía eólica. Los equipos de Investigación y Desarrollo, así como el equipo de asistencia técnica, han trabajado estrechamente con la industria y con todos los principales fabricantes de equipos de energía eólica para desarrollar la tecnología más avanzada que mejora los índices de resistencia / peso y los requisitos de fatiga.
