En los \u00faltimos a\u00f1os, los requisitos de los OEM han evolucionado hacia una mejora de la calidad del aire interior (IAQ), poniendo el foco en la reducci\u00f3n de compuestos org\u00e1nicos vol\u00e1tiles (VOC), el control de aldeh\u00eddos como el formaldeh\u00eddo y la mejora del olor.<\/p>\n

Estas exigencias son especialmente estrictas en Asia, impulsando el desarrollo de nuevas soluciones de bajo VOC, donde los tensioactivos de silicona juegan un papel fundamental.[\/vc_column_text][vc_custom_heading heading_semantic=\u00bbh3″ text_size=\u00bbh4″ uncode_shortcode_id=\u00bb128936″]Objetivo<\/strong>[\/vc_custom_heading][vc_column_text uncode_shortcode_id=\u00bb966321″]Evaluar el impacto de sustituir una silicona convencional por una alternativa de bajo VOC.[\/vc_column_text][vc_custom_heading heading_semantic=\u00bbh3″ text_size=\u00bbh4″ uncode_shortcode_id=\u00bb168328″]Metodolog\u00eda Experimental<\/strong>[\/vc_custom_heading][vc_column_text uncode_shortcode_id=\u00bb824054″]Las pruebas se realizaron todas con la misma formulaci\u00f3n HR de tipo TM y condiciones de moldeo.

\n– An\u00e1lisis a 60\u00b0C

En t\u00e9rminos de TVOC, el sistema con ST1 presenta valores de 11137.998 \u00b5g\/esp\u00e9cimen, mientras que PU-1254 reduce esta cifra a 8550.035 \u00b5g\/esp\u00e9cimen, lo que supone una disminuci\u00f3n aproximada del 23 %. En cuanto al olor, tambi\u00e9n se observa una mejora relevante, pasando de una valoraci\u00f3n de 3.0 con ST1 a 2.5 con PU-1254, equivalente a una mejora cercana al 17 %. Estos datos confirman el papel clave de la silicona en las emisiones y en la percepci\u00f3n olfativa final del material.<\/p>\n

Desde el punto de vista t\u00e9cnico, el cambio de silicona impacta directamente en par\u00e1metros cr\u00edticos como las emisiones de VOC, la formaci\u00f3n de aldeh\u00eddos y el olor final del producto. En este contexto, PU-1254 destaca por permitir mejoras sustanciales en estos aspectos sin necesidad de modificar el proceso ni la formulaci\u00f3n, actuando como una soluci\u00f3n \u201cdrop-in\u201d.[\/vc_column_text][vc_custom_heading heading_semantic=\u00bbh3″ text_size=\u00bbh4″ uncode_shortcode_id=\u00bb944641″]Conclusiones<\/strong>[\/vc_custom_heading][vc_column_text uncode_shortcode_id=\u00bb178470″]El surfactante STB PU-1254 presenta ventajas claras como la reducci\u00f3n significativa de compuestos org\u00e1nicos vol\u00e1tiles (VOC), cercana al 23 %, as\u00ed como una disminuci\u00f3n del formaldeh\u00eddo de aproximadamente un 24 %, lo que contribuye a mejorar la calidad ambiental del producto final. Adem\u00e1s, ofrece una notable mejora en el olor, incrementando el confort percibido. Gracias a estos beneficios, se posiciona como una soluci\u00f3n clave para el desarrollo de espumas PU de HR.<\/p>\n

A nivel industrial, este caso demuestra no solo el potencial de la Serie 1000, sino tambi\u00e9n la capacidad de Concentrol para ofrecer soluciones avanzadas adaptadas a las crecientes exigencias del mercado. La gama de surfactantes de la Serie 1000 est\u00e1 dise\u00f1ada para dar respuesta a todo tipo de sistemas HR, incluyendo formulaciones basadas en TDI, MDI y TM, proporcionando alternativas de bajo VOC que permiten cumplir con los requisitos m\u00e1s exigentes de OEM, especialmente en mercados asi\u00e1ticos. Este enfoque integral posiciona a Concentrol como un socio tecnol\u00f3gico capaz de acompa\u00f1ar a sus clientes en la transici\u00f3n hacia materiales de menor emisi\u00f3n, sin comprometer el rendimiento ni la procesabilidad.[\/vc_column_text][vc_column_text uncode_shortcode_id=\u00bb137991″]En el departamento de I+D+i, desarrollamos soluciones a medida para cada necesidad de nuestros clientes.
