Arkema Plexiglas® ELiT II

Plexiglas ELiT II EDGE-LIT TECHNOLOGY ACRYLIC SHEET Plexiglas ELiT II acrylic sheet is a melt calendared acrylic APPLICATIONS sheet that has the ability to diffuse light coming from light n Poster boxes or light boxes sources located at the edges of the sheet. Light is diffused towards the front face creating bright and evenly illuminated display panels. This effect is achieved through technology that will reorient the light source towards the surface n Illuminated signs for airports subways train stations bus shelters and terminals of the sheet. n Display panels for restaurants hotels department stores banks movie theaters and casinos PRODUCT OFFERING n Menu boards or information directory panels Thickness Sheet Size 0.157 51 x 100 0.197 51 x 120 0.236 0.315 0.394 Custom sizes available upon request. FEATURES n Can utilize either Fluorescent or LED light sources n Edge Lit technology allows for extremely thin frames for light boxes n Can be edge lit from one or two sides depending on sheet size n Weatherability is comparable to standard Plexiglas MC sheet Plexiglas ELiT II EDGE-LIT TECHNOLOGY ACRYLIC SHEET TYPICAL STANDARD PROPERTIES - Plexiglas ELiT II RECOMMENDATIONS TEST METHOD UNIT VALUE n Diamond-polish the edges of Plexiglas ELiT II sheet to maximize the amount of light entering the panel. in 0.197 n Specific Gravity ASTM D-792 --- 1.19 Rockwell Hardness ASTM D-785 M scale 90 When choosing a light source use the highest correlated color temperature available. A 6500K light source best replicates that of daylight. n Place reflective materials such as Mylar films around each light source to maximize the amount of light directed into the sheet edges. This can boost lighting efficiency up to 20. n Utilize metalized reflective adhesive tapes 3M silver polyester film tape 850 to cover the non-illuminated edges to prevent light from escaping the panel. n Avoid gluing or bonding any materials to Plexiglas ELiT II sheet which could inhibit its light transmitting pr

operties. n If forming Plexiglas ELiT II sheet do not exceed a 20 radius of curvature. This will minimize the light diffusing effect. n Be careful not to scratch the surface of Plexiglas ELiT II sheet as this will show up as a bright spot when the panel is lit.
