CNB™ Free Form Film

For applications with touch on 3D surface

Stretchable. Transparent. Low reflectance

CNB™ Free Form Film is a transparent conductive film on Polycarbonate substrate. It enables design freedom for touch interfaces with 3D formed shapes.  CNB™ Free Form film can be stretched to any 3D form that is supported by the Polycarbonate substrate. Read about 3D formability

Due to zero reflectance and haze, and natural color neutrality, it provides for deep black, true white, and excellent contrast in on-display touch use. Read about display readability.

Free Form Film is compatible with industry standard thermoforming and injection molding processes including Film Insert Molding (FIM).

  • Highly stretchable
  • Tight bending radius
  • Thermoformable with pressure or vacuum
  • Back-moldable with PC, PMMA and other resins
  • Non-reflective for good contrast
  • Low resistivity, 60-300 ops
