3DXTech ThermaX Ultem 9085 PEI - Black - 500g

Our PEI-based filaments offer the ability to create parts with excellent properties at elevated temperatures due to a very high glass transition temperature (Tg). Ideal for use in critical applications which require electrostatic discharge (ESD) protection, a high level of cleanliness, and the outstanding thermal and chemical properties you’ve come to expect with PEI based compounds.

Benefits of ThermaX PEI 9085

• High thermal properties, with a Tg of 186°C, HDT 158°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
