Does acrylic (Plexiglas, Lucite) yellow in the sun?
There are many questions about how plastics will handle the elements outside. For most plastics, sunlight especially ultraviolet radiation has a negative effect on the majority of plastics. Many toys made from PE become brittle and crack when left outside. American-made acrylics do not yellow in the Sun. The other clear plastics that do yellow in the Sun are styrene, PETG and Polycarbonate.
