Ultem®/PEI (polyetherimide) film offers high heat resistance, coupled with high mechanical strength, stiffness, UV stability, and broad chemical resistance. This combination of properties proves the ability of this film to be used for a wide variety of demanding new design concepts. Similar to PEEK, Ultem® can be considered a more cost effective solution if continuous temperatures below 338F are acceptable per the application. It has a UL94 flame resistance rating of VTM-0, is FDA compliant, and is thermoformable. Custom sized sheeting available.
