ThermaX PEI Filament (ULTEM™ 9085)

PEI is an amorphous, high-performance polymer which combines excellent thermal properties, exceptional dimensional stability, inherent flame Benefits of PEI 9085 Include: High thermal properties, with a Tg of 186°C Inherently flame-resistant with low smoke evolution and low smoke toxicity Long-term hydrolytic stability Excellent dimensional stability, low heat creep sensitivity, and a very low, uniform coefficient of thermal expansion create highly reproducible part-to-part dimensions Exceptional strength and modulus, even at elevated temperatures Good resistance to a broad range of chemicals, include automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies Typical Applications of ULTEM 9085 PEI: Aerospace: The excellent balance of flame retardancy, low smoke emission, and low smoke toxicity of ULTEM 9085 filament makes it an excellent candidate for aerospace
