Röhm ACRYLITE® LED 8N LD12 Acrylic Molding Compound  (discontinued **)
Categories: Polymer; Thermoplastic; Acrylic (PMMA)
Material Notes: Product Profile: ACRYLITE® LED 8N LD12 Acrylic Molding Compound is a highly transparent light guide material based on ACRYLITE® 8N. In addition to the typical properties of ACRYLITE®, such as
  • Excellent weather resistance
  • UV-stability
  • Good flow, high mechanical strength
ACRYLITE® LED 8N LD12 is developed for edge lit LED applications. The light scattering properties convert the light guide to a full illuminated panel. Furthermore, the material allows for a completely transparent view through the light guide when it is not illuminated. This opens a new degree of freedom for designers. ACRYLITE® 8N LD12 is recommended for panels with a distance of up to 12 cm (4.72 in) between two light injecting LED strips.

Application: Injection molding or extrusion.
