The thermal properties of our products
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 … Read more
What is the heat resistance of asymmetrical diffuser film? Asymmetric diffuser film is designed to withstand heat up to 80C/145F. Exposure at higher temperatures will cause the film to start to melt, and its diffusion lens system will become deformed.
What is the heat resistance of Archival DuraLar™? Archival 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. So if your film will only be exposed to a heat environment below 150C/300F, archvial DuraLar is a good choice. Need to … Read more
What is the heat resistance of Acetate film and sheets? Acetate starts to soften at 100C/210F. The film will soften very evenly which makes Acetate ideal for thermoforming and heat sealing application. If you need an excellent high clarity film that is more heat resistant than acetate, please checkout our Clear DuraLar film and sheet … Read more
Yes, DFML is Thermoformable. However the more you draw this film, the more the micro louvre lens surface gets distorted. This could be a good thing or a bad thing depending on the diffusion you are trying to create. For something like this, it is always best to experiment.
Acetate softens and starts to lose its form at 100C/210F. Softening is also dependent on how long the film is exposed to high temperatures. If you expose the film to a constant elevated temperature, it can lose its physical properties as well. It’s ability to soften at these temperatures makes Acetate ideal for thermoforming … Read more
Can DuraLar be thermoformed? Not really, we can not recommend any of our grades of Duralar for thermoforming applications. Because of it’s higher heat tolerance, and bi-axial crystaline structure, it is not the best choice for thermoforming applications. It’s not impossible but we don’t know many folks using DuraLar for this application.
