SPECIALTY GRADES OF PLEXIGLAS®
ACRYLIC SHEET
Plexiglas^® UF Sheet (Ultraviolet Filter)
Some applications, such as document and fine art preservation, call for a filter material that absorbs more ultraviolet (UV) energy than ordinary glass without absorbing visible light. Plexiglas^® G UF-3 and Plexiglas^® MC UF-5 acrylic sheet absorb 98% of all UV rays, as well as some visible light (see Figure 1), while maintaining the full range of physical properties associated with standard Plexiglas^® sheet. Plexiglas^® G UF-4, developed for mercury vapor lighting applications, can also be used as a protective shield. Plexiglas^® G UF-4 sheet does transmit slightly more UV energy than Plexiglas® G UF-3 and Plexiglas® MC UF-5 sheet.

Plexiglas^® G UF-3 and UF-4 are available in sheet sizes 48" by 96", 60" by 96" and 72" by 96", and in thicknesses of 0.118", 0.177" and 0.236"(3.0, 4.5 and 6.0 mm). Plexiglas^® MC UF-5 is available in a standard sheet size of 48" by 96", and in thicknesses of 0.060", 0.080" and 0.118"(1.5, 2.0, and 3.0mm). Plexiglas^® MC UF-5 is also available in a non-glare finish.
