3D formable and bendable touch films and sensors

Use in any form or surface, mold, bend or stretch with patented carbon nanomaterial technology

CNB™ Films and Touch Sensors are based on Canatu’s proprietary Carbon NanoBud® material, which enable design freedom for touch interfaces with 3D formed shapes.

Carbon NanoBud® material
The Canatu patented materials lend itself well for applications requiring forming or bending: Carbon NanoBud material can be stretched more than 200%, and it can be bent and flexed in tighter radii than 1 mm.   NanoBud molecules are made of carbon which does not reflect any light – this enables touch displays with deep black and high contrast.

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

  • 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

 Display Grade

  • Specially optimized for high performance displays
  • High transmittance 90-98% (substrate normalized)
  • Excellent color neutrality
  • Non-visible sensor patterns
  • Low haze <0.5%

Lighting Grade

  • For illuminated controls and lighting applications
  • Excellent color neutrality

CNB Curve Film

For applications with touch on curved or flat surfaces

Bendable. Transparent. Low reflectance

CNB Curve is a bendable, transparent conductive film on PET substrate. It is designed for touch applications on flat or curved surfaces. Due to zero reflectance and haze, as well as its natural color neutrality, it provides a true black, true white, and excellent contrast for on-display touch sensors.

  • Extremely bendable
  • Flat transmittance spectrum for true colors
  • Non-reflective for good contrast
  • Low haze <0.3%
  • High transmittance 90-98%
  • Non-visible patterns in sensors
  • Low resistivity, 60-300 ops

CNB Touch Sensors

For curved or 3D touch applications

High performing optics. Thermoformable. Bendable

CNB Touch Sensors are built on CNB Free Form or CNB Curve Films. CNB Sensors can be bent to curved forms and formed to 3D shapes. CNB Sensors are designed for standard industrial processes such as Film Insert Molding and optical bonding. These sensors enable complete design freedom and unique user experience to any surface.  CNB Touch Sensors provide a true black, true white, and excellent contrast in touch displays.

CNB Touch Sensors can be used in multiple areas, including:

3D shaped touch lens on display

  • Multitouch
  • 2 CNB sensor layers with CNB Free Form Film
  • Thermoformed into desired free 3D form
  • Optically bonded to seamless front window with decoration and to the display

3D shaped touch sensor with surface features

  • Like controls, touch buttons, smart switches or sliders formed into ergonomic shapes
  • Typically 1 CNB layer with CNB Free Form Film
  • Can have several touch functions in the same sensor sheet
  • Can be integrated in the same sensor sheet as on-display multitouch sensor
  • Bonded to seamless front window with decoration and suitable backlighting
