The ST-100 Series low GWP formulation represents a sustainable technology shift that reduces the product's embodied carbon, meets U.S. state HFC regulations and supports DuPont's 2030 Sustainability Goals. This game-changing formulation is a new grey color instead of the traditional blue — so you’ll know it when you see it.

The Styrofoam™ Brand ST-100 Series has been formulated to meet sustainability goals for climate action regulations in U.S. states. But some things remain unchanged: these new XPS products offer the same high performance and long-term value under the same Styrofoam™ product names with ST-100 descriptor – so there’s no need to change your specifications.
