Trabajando con adhesivo termofusible PUR<\/h2>\r\n <\/div>\r\n <\/div>\r\n

\r\n

Desarrollos recientes en reactivo Poliuretano termofusible<\/span> (HMPUR) adhesive technology have made these products viable candidates for use in high performance applications. Specifically,\r\n technical advantages that combine desirable properties such as past set (curing), rapid green strength development, and exceptional environmental resistance, are now available.<\/p>\r\n <\/div>\r\n <\/div>\r\n

\u00bfQu\u00e9 es PUR Hotmelt (hmpur)?<\/h5>\r\n <\/div>\r\n <\/div>\r\n
\r\n \r\n \r\n
\r\n

Los HMPUR son el producto de reacci\u00f3n de la combinaci\u00f3n de un poliol y un isocianato<\/span>. Once reacted, the product formed is an isocyanate terminate prepolymer, which is moisture\r\n sensitive. After application, this product cross-links through a reaction with moisture in the air and surrounding substrates, forming a thermoset polyurethane polymer. Once thermoset, the HMPUR will possess exceptional\r\n strength and durability. Because these products contain isocyanates and must be heated for application, our partners work with lesser volatile isocyanates, such as MDI (diisocianato de difenilmetano).

\u00bfC\u00f3mo funciona?<\/h5>\r\n <\/div>\r\n <\/div>\r\n
\r\n \r\n \r\n
\r\n

Los HMPUR funcionan mediante dos etapas distintas<\/span> para desarrollar las caracter\u00edsticas de un adhesivo de alto rendimiento. En el primera etapa<\/span>, el HMPUR se calienta para volverse fundido o fluido para su aplicaci\u00f3n. En esta etapa, el HMPUR es similar a los termofusibles convencionales porque el enfriamiento t\u00e9rmico solidifica el adhesivo despu\u00e9s de la aplicaci\u00f3n. En consecuencia, el HMPUR tiene un tiempo abierto y un tiempo de fraguado. Desarrollar\u00e1 suficiente resistencia al enfriarse para permitir el recorte en l\u00ednea y otra manipulaci\u00f3n de las piezas.<\/p>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n

\r\n

En el segunda etapa<\/span>, el HMPUR reacciona con la humedad para formar un pol\u00edmero termoendurecible resistente al calor, la humedad, el fr\u00edo y los disolventes. Esta reacci\u00f3n se produce con el paso del tiempo y, en condiciones normales,\n el curado 75% se alcanza en las primeras 24 horas.\u00a0A medida que contin\u00faa la reticulaci\u00f3n, los sustratos ensamblados seguir\u00e1n ganando resistencia. Condiciones normales: 50% de humedad relativa y 21\u00b0<\/span>C.<\/p>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n <\/div>\r\n

Por favor, p\u00f3ngase en contacto con nosotros si necesita asesoramiento detallado sobre c\u00f3mo trabajar con HMPUR. Hay un enorme alcance<\/span> de diferentes tipos de HMPUR. Por lo tanto, es muy importante entender todos los requisitos de la laminaci\u00f3n antes de elegir el HMPUR adecuado.\r\n

El HMPUR se utiliza para muchas aplicaciones diferentes, principalmente la laminaci\u00f3n. Algunos ejemplos son:<\/p>\r\n

Laminado plano: madera a panel, madera a papel foil, metal a madera, etc.\r\n
\r\n <\/p>\r\n

\r\n \r\n Laminaci\u00f3n flexible<\/u>\r\n <\/a> (de rollo a rollo): De textil a textil, de textil a membrana, de textil a espuma, etc.\r\n
\r\n <\/p>\r\n

Revestimiento de perfiles: de pel\u00edcula a perfil de PVC, de pel\u00edcula a perfil de aluminio, etc.\r\n
\r\n <\/p>\r\n

Ensamblaje: Piezas pegadas a la estructura, etc.\r\n
