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
Aerospace Applications: The excellent balance of flame retardancy, low smoke emission, and low smoke toxicity of Ultem® 9085 makes it an excellent candidate for aerospace and aircraft applications. Ultem® 9085 meets FAR 25.853 and OSU 65/65 with low toxicity, smoke and flame evolution. Ultem® resins are found in applications, such as personal service units, oxygen panels and components, ventilation system components, connectors, cable ducts, latches, hinges, food tray containers, door handles, and interior cladding parts.
Automotive / Transportation Applications: Ultem® resins provide automotive manufacturers with a high performance, chemically resistant, thermally-stable, cost-effective alternative to metal that is strong enough to replace steel in some applications and light enough to replace aluminum in others. For applications like transmission components, throttle bodies, ignition components, sensors and thermostat housings,
Electrical / Electronics Applications: Ultem® resin may be an excellent material choice for today’s demanding electrical applications, including connectors, MCB components like housings, shafts and levers, hard disk drive internals, FOUP’s, BiTS, PCB’s, MCCB internals, Plenum devices, LCD projector internals, fuel cell components and many other applications.
