La coextrusi\u00f3n es el proceso de formaci\u00f3n de un extruido compuesto por m\u00e1s de una corriente de fundido termopl\u00e1stico. Es muy similar a la extrusi\u00f3n de pl\u00e1sticos, pero con la coextrusi\u00f3n se insertan varios pol\u00edmeros en las matrices de extrusi\u00f3n para producir un \u00fanico perfil con distintas caracter\u00edsticas f\u00edsicas.<\/p>\n\n\n\n

Algunas demandas del mercado, en particular de la industria del envasado, no pod\u00edan satisfacerse con un solo pol\u00edmero, aunque s\u00ed con una combinaci\u00f3n de pol\u00edmeros. La coextrusi\u00f3n se practic\u00f3 por primera vez en la producci\u00f3n de pel\u00edculas fundidas y ahora tambi\u00e9n se utiliza en la extrusi\u00f3n de pel\u00edculas sopladas y l\u00e1minas. Normalmente, la intenci\u00f3n es producir una estructura laminar en la que cada capa contribuya con una propiedad clave al rendimiento global del producto. Las pel\u00edculas coextruidas pueden ser estructuras muy complejas compuestas por muchas capas funcionales diferentes, incluidas capas de uni\u00f3n cuya finalidad es unir capas vecinas de compatibilidad limitada.<\/p>\n\n\n\n

Coextrusion is the process of forming an extrudate composed of more than one thermoplastic melt stream. It’s very similar to Plastic Extrusion,however, with co-extrusion you are inserting multiple polymers into the extrusion dies to produce a single profile with a range of physical characteristics.
