3DXSTAT ULTEM™ PC-PEI
PEI is an amorphous, high-performance polymer that combines excellent mechanical, thermal, and chemical resistance properties. 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 that 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.
Product attributes include:
- 10^6 to 10^7 ohm surface resistivity on 3DP sample using concentric ring test method
- Consistent surface resistivity
- Low particulate contamination
- High thermal properties
- Inherent flame resistance
- 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
