Polyether Imide (PEI)

Based on 591 products - Last update on the Jun 26, 2025

Polyether Imide (PEI) is a high-performance thermoplastic that appears as a smooth, amber-colored material. Its chemistry provides exceptional thermal stability, mechanical strength, and chemical resistance. Key features include high heat resistance, excellent electrical insulation properties, and good dimensional stability. Main applications of PEI are in aerospace, automotive, and electronics industries. 

Alternatives to PEI include PEEK and polyimide. A trend in this technology is the increasing use of PEI in 3D printing and additive manufacturing due to its excellent processability and performance. Sub-types of PEI include reinforced grades for added strength and impact resistance.
