The 3M flexible insulation papers are designed with very different properties. When the pure papers lacks a specific properties, we are able to offercustomized laminates by selecting the appropriate combination of paper and substrate.
The most frequent materials used for lamination are PET and Polyimide Film but also engineering plastics such as Polycarbonate, PMMA or COC films can be used. For applications with very high tensile strength laminates with Glass Cloth Backing are available.
