Material Properties

Continuous use temperature rated to 265°F. Lightweight with high dielectric strength and superior UV resistance for outdoor applications. Low moisture absorption and high light transmission — ideal for custom sign shapes and sizes requiring impact resistance where acrylic would crack or shatter.

Applications & Uses

The preferred substrate for illuminated sign faces, backlit cabinet signs and day/night sign applications. Sign-grade polycarbonate transmits light evenly for consistent backlit results — ideal for channel letter faces, lightbox inserts and outdoor directional signs. Suitable for high-traffic environments where impact resistance is critical.

Compatible with Oracal 651 vinyl lettering without additional priming. For alternative rigid sign substrates see our acrylic sign sheets, aluminum sign sheets, ACM sign sheets and styrene sheets.
