According to our (Global Info Research) latest study, the global Polyetherimide (PEI) market size was valued at US$ 664 million in 2025 and is forecast to a readjusted size of US$ 871 million by 2032 with a CAGR of 4.2% during review period.
Polyetherimide (PEI) is an amorphous, amber-to-transparent thermoplastic with characteristics similar to the related plastic PEEK. Relative to PEEK, PEI is cheaper, but is lower in impact strength and usable temperature.
PEI is a high-performance engineering plastic characterized by exceptional high-temperature resistance and dimensional stability, as well as chemical resistance, flame retardancy, excellent electrical properties, high strength, and high rigidity.
PEI resin is widely used in applications such as high-temperature terminals, IC sockets, lighting equipment, FPCBs (flexible printed circuit boards), fluid handling equipment, aircraft interior components, medical devices, and household appliances.
PEI Market Drivers
1. Trend toward high-temperature operation and miniaturization in electrical and electronic equipment
Components such as electronic connectors, relays, chip testing equipment, fiber-optic connectors, 5G base stations, and data communication equipment demand materials that can maintain dimensional stability during reflow soldering and in long-term high-temperature environments, retain sufficient mechanical strength even with thin-wall designs, and offer flame retardancy and low smoke emission. SABIC has positioned its PEI products for applications including 5G infrastructure, AI equipment, smart electronics, robotics, and high-performance electrical systems; the electrical and electronics sector is a primary source of demand for PEI.
2. Expansion of new energy vehicles (NEVs) and high-voltage electrical systems
NEVs have increased the demand for highly heat-resistant insulating materials in components such as high-voltage connectors, inverters, electric motors, batteries, charging equipment, and thermal management systems. PEI combines heat resistance, electrical insulation, low warpage, and precision molding capabilities, making it well-suited for trends toward vehicle electrification, as well as the miniaturization and lightweighting of ADAS (Advanced Driver Assistance Systems).
3. Lightweighting and flame retardancy requirements in aerospace
Aircraft interiors and onboard equipment require not only weight reduction but also compliance with strict FST (Flame, Smoke, and Toxicity) performance standards. PEI’s inherent flame retardancy, low smoke emission, and high specific strength enable it to replace certain aluminum, steel, and thermoset materials.
