Ultem PEI Polyetherimide Amorphous Polymer Heat and Flame Resistance 3D Printing Heat Bed 3D Printer Build Surface

Ultem/ PEI (polyetherimide) is a high-strength amorphous polymer with excellent heat and flame resistance (carrying a flammability rating of 94-V-0) with little smoke output. It performs continuously, making it superior to commodity plastics such as Nylon and Delrin®. Ultem® is an ideal solution for applications that require high strength and the ability to withstand high temperatures. The product also suits applications that require consistent dielectric properties over a wide range of frequencies. Ultem® is hydrolysis resistant and highly resistant to acidic solutions and is able to tolerate repeated autoclaving cycles, such as with repeated steam sterilization of reusable medical devices. Ultem® is widely used in electronics because of its good arc resistance and dielectric constant. Other typical applications include analytical instrumentation and structural components that require high strength and rigidity at elevated temperatures.
