Aplicaciones principales<\/h3>\n

Plastificante principal para el PVC:<\/strong> La aplicaci\u00f3n m\u00e1s habitual del DOTP es como plastificante principal del cloruro de polivinilo (PVC). Aporta una excelente flexibilidad, resistencia a las bajas temperaturas y resistencia a la intemperie a los productos de PVC, al tiempo que mantiene una elevada resistencia mec\u00e1nica. Se utiliza ampliamente en cables, tuber\u00edas y perfiles de PVC, en cuero artificial, en suelos y en productos m\u00e9dicos de PVC (por ejemplo, tubos de infusi\u00f3n y bolsas de sangre).<\/p>\n

Modificador de pol\u00edmeros:<\/strong> Se utiliza como modificador de las resinas ABS, PS y de poliuretano (PU), mejorando su tenacidad, resistencia al impacto y rendimiento en el procesamiento. Tambi\u00e9n se emplea en elast\u00f3meros termopl\u00e1sticos (TPE) para mejorar su elasticidad y durabilidad.<\/p>\n

Recubrimientos y adhesivos:<\/strong> Se a\u00f1ade a los recubrimientos industriales, las pinturas para autom\u00f3viles y los adhesivos estructurales como agente coalescente y disolvente plastificante, mejorando las propiedades de formaci\u00f3n de pel\u00edcula, la adhesi\u00f3n y la resistencia al agua, a los productos qu\u00edmicos y a la radiaci\u00f3n UV.<\/p>\n

Aditivo para lubricantes y grasas:<\/strong> Se utiliza como aditivo en aceites y grasas lubricantes para mejorar el \u00edndice de viscosidad, el rendimiento antidesgaste y la estabilidad a altas temperaturas. Es especialmente adecuado para lubricantes de alto rendimiento destinados a la automoci\u00f3n y la maquinaria industrial.<\/p>","protected":false},"excerpt":{"rendered":"

El tereftalato de dioctilo, com\u00fanmente abreviado como DOTP, es un plastificante de \u00e9ster arom\u00e1tico de alto rendimiento sintetizado a partir de \u00e1cido tereft\u00e1lico y 2-etilhexanol.
