Polyetherimide or PEI is the generic name for one of the popular engineering resins. The most common resin supplier for this material is Sabic Plastics (formerly known at G.E. Plastics). This material comes in two common varieties used in the production of plastic shapes, the first is Ultem® 1000 which is an unfilled – natural material, the standard color for unfilled PEI (Ultem Sheet) is a transparent amber. The second is Ultem® 2300, which is a 30% glass filled PEI resin, this resin is a creamy tan color. Several other resins are available, including different percentages of glass fill, black pigment or color, and a few high end specialty grades.
Ultimate Ultem 1000
Some members our our industry refer to Ultem® as the ‘ultimate’ in plastic materials. With some of the best available properties, this material out performs most plastics in critical applications. This material is certified to: FDA compliance, USDA, 3A and also USP Class VI for medical use. Polyetherimides have exceptional tensile and flexural strengths and excellent electrical properties. Ultem® resins have inherent flame resistance and are UL 94 5VA at .075″. Ultem Sheet and rod machines very well, and can be used at temperatures of 340 degrees continuous.
Polyetherimide – PEI is the Ultimate Resin
The Polyetherimide family of plastic resins really excel in the medical and pharmaceutical industries. These industries have incredible demands on plastic materials, and most plastics fail quickly. Ultem resins handle the heat, chemical, stress better than almost any other material. For complete technical data sheets and more information chick for data sheet page. Several of our major manufacturers produce Ultem® PEI resins into stock sheets and rods. Some trade names from these suppliers are: Unitem®, Tempalux®, Sustatec® and many more. Ultem sheet and rod has some of the best properties of all the available plastic materials. Some materials that have some similar properties: Acetal, Radel, PEEK, PTFE. Check the data sheets on each of these materials to help in deciding which material is appropriate for your application.
Rod is normally available in rod from .375″ – 4.0″ diameters, and sheets from .125″ – over 2.0″ thickness, and we stock many items for immediate shipment. Additional sizes are available on request, including larger diameters, thicknesses, molded tube, extruded shapes, strips and bars.

Gehr Plastics has been a major global manufacturer in the plastic sheet and rod industry since 1932. During this period, Gehr has become a leader in a variety of product lines, and also become known for very large sizes in both sheet and rod. Currently Gehr can produce Acetal rod up to 20″ in diameter and sheets up to 8″ thick. Some of the many plastic materials the Gehr produces:
Radel Rod is produced in many medical grade colors
Being innovative also means looking forward. Gehr was selected as the Bioplastics manufacturer of the year in 2008, partly for the new line of plastic materials which have a bio base. These materials have a variety of bio based forms, including: a PLA base, Cellulose based, Polyamide and Wood – Plastic Composite (WPC). One such material is ECOGEHR PLA-L which is a blend of polylactic (polylactic acid), some lignine, fatty acid and wax. This biopolymer is new to our industry and can be used in temperatures ranging from -22 °F to +140 °F.This complete line of materials is one of the only available in the plastic industry to be comprised of many renewable raw materials. Gehr leads the way in this exceptional and innovative product line.
ClearGehr Polyamide Rod
This brand new product is a Clear Polyamide rod. The outside surface is as extruded, and can be polished. This enables the production of a relatively clear sight glass quality material with most of the high end properties of Polyamide – Nylon material. We have supplied this material for small machined parts where neither Polycarbonate nor Acrylic would work well. Because of the natural inherit chemical resistance of Polyamide, this high end ClearGehr rod can out perform all normal transparent plastics. Give us a call to see if this new innovative product will work in your difficult application.
FDA Approved Wear Grade Acetal
Have you been looking for an extended wear Acetal material (like the PTFE filled Acetals – Delrin AF), but need it to be FDA approved? Then perhaps you should consider WearGehr. This propriatary filled Acetal material has excellent wear resistance, and retains the FDA approval of the base Acetal, unlike the PTFE filled Acetals which are not FDA approved. It is made in a blue color for easy identification, also it remains very machinable.
