Rigid and Durable Sheet Solutions

Looking for materials that are both tough and weatherable? You’re in the right place. When it comes to signage and glazing applications, you want a material that will stand up to the demands of forming, fabrication and installation. And once installed, you need a material that holds up over time. Our UltraTuf® formulations are designed for class-leading performance in these critical areas.

UltraTuf® SG Copolyester Sheet

UltraTuf® SG, processed using Eastman Tritan copolyester, is an ideal material for signage and glazing applications. Its strength and versatility provides ease of fabrication using many techniques, including thermoforming, cutting and routing. Due to excellent formability at low temperatures, UltraTuf SG can be easily thermoformed after decoration with vinyl graphics and screen inks. In addition, UltraTuf SG usually doesn’t require pre-drying. Choose UltraTuf SG when extreme toughness combined with ease of fabrication is essential to your project.
