Ultem 9085 is a high-performance thermoplastic resin specifically formulated from polyetherimide (PEI). Renowned for its excellent balance of mechanical properties, high heat resistance, and flame retardancy, Ultem 9085 is predominantly utilized in additive manufacturing. As a PEI material, it exhibits exceptional thermal stability and retains its performance in demanding environments, making it suitable for aerospace, automotive, and military applications. The material’s lightweight yet strong composition allows for the production of robust end-use parts and prototypes, meeting stringent regulatory standards such as FAR 25.853 and OSU 65/65 for flame, smoke, and toxicity. Its inherent robustness, coupled with its precision and reliability, makes Ultem a preferred choice in industries requiring high durability and exacting standards.
