备注说明 | ACRYLITE® LED 8N LD96 Acrylic Molding Compound is a highly transparent light guide material based on ACRYLITE® 8N.In addition to the typical properties of ACRYLITE®, such as ACRYLITE® LED 8N LD96 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 48 cm to 96 cm between two light injecting LED strips.Application:Injection molding or extrusion. |
