La pel\u00edcula de acetato de vinilo<\/strong> de etileno (EVA) <\/strong>y la pel\u00edcula polivinilbut\u00edrica<\/strong> \u00a0(PVB)<\/strong> son dos materiales polim\u00e9ricos diferentes, pero ambos se pueden utilizar para vidrio laminado.<\/p>\n

El PVB ha sido durante muchos a\u00f1os el material de referencia para laminaci\u00f3n de vidrio en la industria de la construcci\u00f3n y el transporte, pero el EVA en los \u00faltimos a\u00f1os est\u00e1 ganando terreno gracias a sus propiedades que en algunos casos son mejores que el PVB.<\/p>\n

Una de las principales diferencias entre EVA y PVB es la velocidad de transmisi\u00f3n de vapor de agua, resultante del agua natural o la humedad atmosf\u00e9rica. El PVB es sensible a la humedad y est\u00e1 m\u00e1s expuesto a problemas como la infiltraci\u00f3n de agua en las esquinas del vidrio laminado, por lo tanto, al riesgo de delaminaci\u00f3n.<\/p>\n

La composici\u00f3n qu\u00edmica termo-endurecedora de EVA permite que las mol\u00e9culas internas generen conexiones tridimensionales, asegurando as\u00ed un grado adicional<\/strong>de protecci\u00f3n para todos los elementos arquitect\u00f3nicos expuestos a condiciones excepcionales, como altastemperaturas, alta humedad y condiciones clim\u00e1ticas extremas.<\/p>\n

\u00bfCu\u00e1les son las ventajas de la pel\u00edcula a base de EVA?<\/p>\n

\u2013 Tasa de reticulaci\u00f3n superior al 94%*<\/strong>: el EVA es un material termo-endurecedor y tiene excelentes propiedades termo mec\u00e1nicas, lo que le da durabilidad y estabilidad muy por encima de cualquier termopl\u00e1stico.<\/p>\n

\u2013 Mejor \u00f3ptica: valores de transparencia muy altos.<\/p>\n

\u2013 Mejor resistencia a la humedad: El EVA no es un material higrosc\u00f3pico, por lo que es m\u00e1s resistente a la humedad que el PVB que sufre de un alto grado de absorci\u00f3n de vapor de agua. El EVA no est\u00e1 sujeto a este proceso.<\/p>\n

\u2013 Excelente aislamiento ac\u00fastico: dado el alto grado de insonorizaci\u00f3n es el producto ideal para zonas ruidosas.<\/p>\n

\u2013 Alto Filtrado UV: el filtrado UV al 99% hasta 390nm de longitud de onda es una indicaci\u00f3n de su idoneidad para proteger contra los rayos solares.<\/p>\n

\u2013 Menores costes de transformaci\u00f3n: se puede producir un vidrio laminado con pel\u00edcula EVA en hornos de convecci\u00f3n, como el <\/strong>Lamijet<\/strong> Convection,<\/strong><\/a>\u00a0<\/strong>o por infrarrojos como el Lamijet<\/strong> <\/a>04-2c; <\/strong>estos hornos son de peque\u00f1o tama\u00f1o y accesibles incluso para las peque\u00f1as y<\/a> medianas empresas del sector.<\/p>\n

El procesamiento con pel\u00edcula PVB necesita una c\u00e1mara especial de temperatura controlada y el vidrio debe procesarse en un autoclave, una m\u00e1quina costosa y grande adecuada para empresas de gran volumen.<\/p>\n
