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

Ultem l000 polyetherimide is an amorphous polymer offering high strength and excellent flame and heat resistance. It 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. It is hydrolysis resistant, highly resistant to acidic solutions and capable of withstanding repeated autoclaving cycles.

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

Ultem 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.

Port Plastics offers Ultem 1000 and Ultem 2300 as standard products, and will custom quote Ultem 2100, 2200 and specialty grades of Ultem.

Application

Structural probes - Surgical probes machined from Ultem rod are autoclavable, and offer high strength and rigidity. (Prior materials: Acetal, Polysulfone)

Manifolds - In pharmaceutical process equipment, manifolds machined from Ultem plate offer resistance to hot chemical solutions and daily sanitizing. (Prior material: Aluminum)

Insulators - High frequency insulators used in microwave communications equipment are machined from Ultem stock shapes. (Prior material: Ceramic)

Clamps - High voltage and flame resistance of Ultem make it ideal for clamps used to connect printed circuit boards to video display units used in airplanes, tanks and ships. (Prior material: Acetal)

Engineering Notes:
Since Ultem 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.
