When searching for an ideal material, OEMs of the of the light source system, Panasign Co. Ltd., Jinba Co. Ltd. and Ziyoumei Co. Ltd. turned to Covestro and Makrolon® polycarbonate sheet.

To meet the project requirements, the LED light source needed a uniform diffusion material that offered 50 percent light transmission. Covestro developed Makrolon® UV2 polycarbonate sheet diffusion sheet in 4 millimeter thickness, which offers 55 percent light transmission and excellent diffusion properties. This eliminated the "ribs pattern" phenomenon and produced attractive, attention-grabbing advertisements. The high light transmission helps to reduce the use of an LED light source, resulting in energy savings.

The light boxes also utilize Makrolon® UV2 polycarbonate clear sheet in 6 millimeter thickness. With high impact resistance and durability, this sheet material protects the advertisements against damage.

The end result is attractive, eye-catching metro advertising with high-impact backlit panels.

The main properties of Makrolon® UV2 polycarbonate sheet are:

  • Light transparency
  • Impact strength
  • Flame retardance
