产品描述
ACRYLITE® LED 8N LD48 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 LD48 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 competely 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 24 cm to 48 cm (9.45 in to 18.9 in) between two light injecting LED strips.
Application:
Injection molding or extrusion.
