Ultem™ 9085 PEI (Polyether Imide) is an amorphous, high-performance polymer that combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy, and good chemical resistance. Ultem™ 9085 resin offers the ability to create parts with excellent properties at elevated temperatures due to a high glass transition temperature (Tg) of 186°C.
Product attributes include:
High thermal properties; (Tg) of 186°C
Inherent flame resistance with low smoke evolution and low smoke toxicity
Long-term hydrolytic stability
Excellent dimensional stability (low creep sensitivity and low, uniform coefficient of thermal expansion) and highly reproducible part-to-part dimensions
Exceptional strength and modulus, even at elevated temperatures
Good resistance to a broad range of chemicals, such as automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies
