Zur Nachbehandlung wird die Folie 24 Stunden bei 8O0C getempert. Die Folie hat durch diese Behandlung infolge eingetretener Vernetzung weichgummiartigen Charakter erhalten.For the aftertreatment, the foil is annealed for 24 hours at 8O 0 C. As a result of this treatment, the film has acquired a soft rubber-like character as a result of the crosslinking that has occurred.
Je nach dem gewünschten Weichheitsgrad der Folie kann man der Lösung der Schiffschen Base aus dem Diamin und dem Aldehyd oder Keton zur Vermeidung einer zu starken Ausschwemmung des Weichmachers aus der Folie noch Weichmacher zusetzen.Depending on the desired degree of softness of the film, one can use the solution of the Schiff base from the Diamine and the aldehyde or ketone to avoid excessive washing out of the plasticizer add plasticizer from the film.
