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.

Not all acrylics are created equal.

Aristech Acrylics® Continuous Cast Acrylic outperforms polycarbonate, extruded acrylic and other polymers – making it the overall best material choice for longer-lasting signs.

  • Greater UV resistance than UV-treated polycarbonate
  • Polycarbonate becomes brittle over time after exposure to UV
  • Superior thermoforming: unlike polycarbonate, our continuous cast acrylic does not require drying prior to thermoforming – performing better than extruded acrylic and polycarbonate
  • Greater manufacturability: continuous cast acrylic is easily routed, does not require special resin for trim capping of channel letters (vs. polycarbonate), and does not warp, shrink or expand like extruded acrylic
  • Custom and wide sheets to minimize scrap cost
  • Excellent color-matching ability and consistency
  • Exceptional light transmission
  • Extreme temperature and UV resistance over the long-term
The best and the brightest.

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.
