What is the heat resistance of Metallized DuraLar™ film and sheets? Metallized DuraLar will begin to soften at about 150C/300F. When Metallized DuraLar softens, it begins to lose its orientation; the metal coating will crack, and the film gets wavy and begins to shrink. So if your film will only be exposed to a heat environment below 150C/300F, Metallized DuraLar is a good choice.
Need to thermoform? Polyester films like Metallized DuraLar don’t thermoform too well because of their crystalline structure. Try our Clearlay, Acetate, HDPE and Polypropylene sheets and film for your thermoforming applications.
