What causes micro cracks in Eva panels?
In the production process, micro cracks most frequently occur during lamination of the panel, especially when using certain EVA films with weak moisture impermeability. If in such cases even slight moisture occurs it cannot easily evaporate which is particularly problematic in hot areas and environments.
