General Info
GEHR PEI Natural is a high-performance, amorphous polyetherimide (PEI) thermoplastic that offers mechanical strength combined with excellent chemical and heat resistance. Designed to withstand continuous operating temperatures up to 170°C (338°F), this material delivers outstanding dimensional stability and creep resistance, making it ideal for precision parts that must maintain their shape and performance under stress.
GEHR™ PEI Natural’s unique torque strength allows it to replace machined metal components, like steel, in small parts and assemblies cost-effectively. This substitution reduces weight, enhances corrosion resistance, and lowers manufacturing costs.
Manufactured to strict quality standards and available in rods, GEHR™ PEI Natural is perfectly suited for industries requiring durable, heat-resistant, and chemically stable materials—including aerospace, automotive, medical, and electrical applications. With Boedeker’s technical support and custom fabrication capabilities, this thermoplastic ensures reliable performance and cost-effective solutions for your most demanding projects.
Note:
- NSF Certification: GEHR™ PEI Natural rod is certified to NSF Std 51 (food zone).
- Note: This does not certify a finished part made from this material for the NSF specification; that is the responsibility of the customer, who will work directly with NSF on certifying the part.

Resin Trade Names
Manufacturer Trade Names
Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
