Se utiliza ampliamente en las industrias del pl\u00e1stico, los recubrimientos y la electr\u00f3nica debido a su extraordinaria transparencia, resistencia a la intemperie y propiedades mec\u00e1nicas.<\/p>\n

Aplicaciones principales<\/h3>\n

Producci\u00f3n de polimetilmetacrilato (PMMA) (uso principal):<\/strong> El MMA se polimeriza para formar PMMA, un termopl\u00e1stico transparente conocido como vidrio acr\u00edlico. El PMMA se utiliza ampliamente en carcasas de luces de autom\u00f3viles, claraboyas de edificios, paneles de visualizaci\u00f3n, lentes \u00f3pticas y productos electr\u00f3nicos de consumo (por ejemplo, pantallas de tel\u00e9fonos inteligentes) debido a su alta transmitancia de la luz (92%), su resistencia a la intemperie y su resistencia al impacto.<\/p>\n

Recubrimientos y adhesivos:<\/strong> El MMA es un mon\u00f3mero fundamental para los recubrimientos acr\u00edlicos al agua, que se utilizan en recubrimientos arquitect\u00f3nicos, repintado de autom\u00f3viles y recubrimientos anticorrosivos industriales. Mejora la adherencia, el brillo y la resistencia a los ara\u00f1azos del recubrimiento. Los adhesivos a base de MMA se utilizan para unir pl\u00e1sticos, metales y vidrio.<\/p>\n

Copol\u00edmeros y resinas modificadas:<\/strong> La copolimerizaci\u00f3n del MMA con el estireno da lugar a resinas de estireno-metacrilato de metilo (SMMA), que presentan una mayor resistencia al calor que el poliestireno y se utilizan en electrodom\u00e9sticos y materiales de embalaje. La copolimerizaci\u00f3n con cloruro de vinilo mejora las propiedades de procesamiento y la tenacidad de los productos de PVC.<\/p>\n

Otros usos:<\/strong> El MMA se utiliza en la fabricaci\u00f3n de materiales para pr\u00f3tesis dentales (resinas acr\u00edlicas dentales) debido a su biocompatibilidad y moldeabilidad. Tambi\u00e9n se emplea en tintas curables por UV, resinas para impresi\u00f3n 3D y agentes de apresto textil.<\/p>","protected":false},"excerpt":{"rendered":"
