What is the heat resistance of Clear DuraLar? Clear DuraLar will begin to soften at about 150C/300F. When DuraLar softens, it begins to lose its orientation; it gets wavy and begins to shrink.
Need to thermoform? Polyester films like Clear 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.
