Plexiglass Acrylic Sheet - UV Filtering

Ultraviolet plexiglass sheet formulations reduce damaging UV light waves.

Within the Ultraviolet Spectrum, UVB (short wavelength high frequency) & UVA (long wavelength low frequency) are the two types of UV light that most concern us. Referencing the table below, general purpose acrylic naturally filters all UV light below 345nm (100% UVB), but only 35% of UVA light. Similarly, ordinary window glass passes about 90% of the light above 350nm, but blocks over 90% of the light below 300nm. Many applications, such as document, artifact, and artwork preservation call for a material which absorbs ultraviolet light in its most damaging range from 285nm to 400nm.

Many pigments and dyes absorb UV and change color, so paintings and textiles may need extra protection both from sunlight and fluorescent bulbs, two common sources of UV radiation. Old paintings such as watercolors must be placed away from direct sunlight if they do not have UV protection. These factors are why many museums place black curtains over watercolor paintings and ancient textiles.
