- High dielectric strength   - Available in glass-reinforced grades
- UL 94-V-0 rated with low smoke   - High strength and performs in continuous use to 340°F (170°C)

Duratron® PEI 1000 (Ultem® l000 polyetherimide) is an amorphous polymer offering high strength and excellent flame and heat resistance. Duratron® PEI performs continuously to 340°F (170°C), making it ideal for high strength/ high heat applications, and those requiring consistent dielectric properties over a wide frequency range. Duratron® PEI is hydrolysis resistant, highly resistant to acidic solutions and capable of withstanding repeated autoclaving cycles.

Duratron® PEI 2100, 2200 and 2300 are glass-reinforced versions (10, 20, and 30%, respectively) of Duratron® PEI 1000 which provide even greater rigidity and improved dimensional stability while maintaining many of the useful characteristics of basic Duratron® PEI. Duratron® PEI 1000 is FDA and USP Class VI compliant. FDA compliant colors of Duratron® PEI are also available on a custom basis.

Duratron® PEI commonly is machined into parts for reusable medical devices, analytical instrumentation, electrical/electronic insulators (including many semiconductor process components) and a variety of structural components requiring high strength and rigidity at elevated temperatures.

Quadrant offers Duratron® PEI 1000 and Duratron® PEI 2300 as standard products.

Proven applications include:

  • Structural probes
  • Manifolds for pharmaceutical processing
  • High frequency insulators for microwave equipment
  • Clamps connecting video display units with PCB's


Since Duratron® PEI is an amorphous material, selection of appropriate non-aromatic coolants during machining is important. Care must also be used in selecting adhesives and designing press fit components to avoid stress cracking. Call Cope Plastics for assistance. Duratron® PEI is not designed for use in bearing and wear applications.
