Röhm PLEXIGLAS® Edgelight 8N LD24 PMMA
Categories:	Polymer; Thermoplastic; Acrylic (PMMA)
Material Notes:	PLEXIGLAS® Edgelight 8N LD24 is a highly transparent light guide material based on PLEXIGLAS® 8N In addition to the typical properties of PLEXIGLAS®, such as Excellent weather resistance UV-stability Good flow, high mechanical strength PLEXIGLAS® Edgelight 8N LD24 is developed for edge lit Edgelight 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. PLEXIGLAS® Edgelight 8N LD24 is recommended for panels with a distance of 12 cm to 24cm between two light injecting Edgelight strips. Application: Preferably, for injection molding, but can also be used for special extrusion. Information provided by Roehm America LLC
