Both our Impact Modified Acrylic (Acrysteel®) and our General Purpose Acrylic (GPA) offer excellent light diffusion, powerful UV resistance, the strength and color consistency you need, and the custom-sizes you want. If you're looking for a sign, then Aristech Acrylics® is the clear choice.
Aristech Acrylics® Continuous Cast Acrylic outperforms polycarbonate, extruded acrylic and other polymers – making it the overall best material choice for longer-lasting signs.
Laboratory testing of polycarbonate, extruded acrylic and Aristech Acrylics® Acrysteel® and GPA products shows that over a period equivalent to 2 years outdoors in Florida, both Aristech Acrylics® products scored higher on the light transmission scale than extruded acrylics and far higher than polycarbonates. A measure of yellowness index shows UV-treated polycarbonate yellowness increased exponentially and quite dramatically over time, whereas both extruded and Aristech Acrylics® yellowness grew at a far less dramatic rate.
