Ultem® 1000 PEI Rod (polyetherimid)-as manufactured by Quadrant Engineering Plastic Products is is an amorphous polymer offering high strength and excellent flame and heat resistance. It performs continuously to 340° F (171°C), making it ideal for high strength/high heat applications, and those requiring consistent dielectric properties over wide frequency. It is hydrolysis resistant, highly resistant to acidic solutions and capable of withstanding multiple autoclaving cycles. Ultem® 1000 is FDA, NSF, USDA and USP Class VI compliant. FDA compliant colors of Ultem are also available on a custom basis. Ultem is commonly machined into parts for reusable medical devices, analytical instrumentation, electrical/electronic insulators and a variety of structural components requiring high strength and rigidity at elevated temperatures.

Ultem® resin is manufactured by GE Plastics -Modern Plastics is a GE Technical Solutions Network Member (TSN), and has vast technical expertise of GE Plastics materials. Contact us for engineering solutions with GE Plastics materials.

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. For expert machining and bonding of Ultem parts contact Eastern Plastics, Inc.
