CNB™ In-Mold Film

CNB™ In-Mold Film
Transparent conductive film optimized for 3D formed capacitive touch displays and touch surfaces in
smart watches, white goods control panels, automobile center consoles and dashboards, connected
user interface devices and curved portable electronic devices. CNB™ In-Mold Films can be easily
formed into shape using standard industrial In-Mold processes such as Film Insert Molding (FIM).
CNB™ In-Mold Film benefits:
Next generation 3D formed touch devices:
Enables new creative industrial designs
• With bending radius below 1mm and stretchability up to
120% CNB™ In-Mold Films enable virtually unlimited
design freedom
• Mobile phones with touch on curved edges
• Smart watches with touch on curved and
flexible surface
• Shaped user interface panels for white
goods
• Curved car dashboards and center consoles
• Input devices with 3D shapes (e.g.mouse)
• Game devices with touch
Replaces mechanical controls with touch
Simple sensor manufacturing process
• Using industry standard processes for thermo-forming
and injection molding
