According to the UnivDatos Market Insights, as per their “Polyetherimide Market” report, the global market was valued at USD 684.49 million in 2024, growing at a CAGR of about 5.99% during the forecast period from 2025 - 2033 to reach USD million by 2033.

The polyetherimide market continues to grow as manufacturers seek out strong, lightweight plastics with high-temperature and intense-use tolerance. Polyetherimide (PEI) is available to customers in pellet, sheet, rod, and film form and can be molded, pressed, or 3-D-printed into final products. Car makers are using it to manufacture lighter dashboards, battery boxes, and under-hood connectors; aerospace companies are incorporating it into cabin panels and air ducts, and electronic companies are using it to create phone lenses, 5 G antenna covers, and small sockets that have to remain steady when hot. Since PEI can substitute metal, keep it naturally flame-resistant, firms are decreasing vehicle mass, fuel consumption, and implementing stronger regulations on recycling and hazardous materials. The resin is also preferred in hospitals and food processors due to its ability to withstand the rigorous process of repeated steam cleaning without compromising its strength. The world suppliers continue to introduce lower‑flow, fiber-reinforced grades, and the recently growing 3D-printing industry is being supplied with new powder and filament products. With governments choosing to stimulate electric cars, more environmentally friendly airplanes, and rapid communication devices, PEI ranks high in terms of its unsurpassed durability and light weight, long life, which are all likely to ensure that the market continues to rise and shine worldwide.

Light-weighting & Metal Replacement in EVs and Aircraft Fueling Market Expansion

Light-weighting and metal substitution on EVs and planes is the most potent demand driver of PEI since each kilogram spared boosts the EV range or reduces jet fuel burn. Glass- or carbon-fiber-reinforced PEI is changing the auto makers as they replace aluminum or thermosets in battery module frames, bus-bar insulators, high-voltage connectors, inverter housings, and coolant manifolds, frequently reducing parts weight by 30 40 percent yet remaining UL 94 V-0 flammability and high dielectric-strength approved. As an example, an EV Tier-1 converted an aluminum bus-bar support to GF-PEI, reducing weight by ~35% and avoiding secondary machining with an injection one-shot mold. Cabin interior manufacturers have started to thermoform PEI sheets into ducting, PSU panels, and seat parts that meet the FAR 25.853 smoke/toxicity requirements in aerospace. They are lighter and easier to recycle than heavier metal or phenolic composites. The need for regulators to tighten the standards of their metrics on CO2 and fuel efficiency, and the OEMs to electrify more of their platforms, continues to suck PEI into new designs due to its structural performance at reduced weight and without halogenated flame retardant.

Latest Trends in the Polyetherimide Market

Rapid Adoption in Additive Manufacturing

Polyetherimide (PEI) is an extremely strong and high-temperature plastic that has found applications in a wide variety of industries, including aerospace, automobile, and medical. One notable trend is the rapid and expanding adoption of 3D printing, or additive manufacturing, to print parts in PEI. This is achieved because 3D printing enables individuals to print sophisticated and customized shapes faster and with less waste in most cases at a lower cost than what traditional manufacturing processes would require.

PEI is an excellent recipient of a 3D print as it can withstand strong temperatures, it is very durable, and it is not easy to break. This makes it applicable in components that should have a long lifespan even under extreme conditions. To illustrate, airplane parts, parts of cars, and even medical tools are made using PEI.

The ease of 3D printing machines today, as well as the fact that they are more sophisticated, is encouraging other firms to adopt the use of PEI on their products. It also supports faster testing of new designs, and this accelerates product development. The fairly steep increase in the application of 3D printing with PEI is transforming the productivity of the products and saving businesses time and money as they produce superior and more reputable pieces. Therefore, rapid adoption in additive manufacturing is a key trend in the polyetherimide market.

Rising Investments in Polyetherimide to Meet High-Performance Industry Demands

The global polyetherimide market is experiencing an increase in investment due to an upsurge in demand in high-performance industries, e.g., aerospace, electronics, automotive, and healthcare. Investors have centered their attention on capacity additions, viable innovations, and compounding factories able to incorporate the elevated need for reinforced and augmented grades of PEI, specifically in the Asia-Pacific and the North American regions. The strongest PEI segment already controlled about 45 per cent of the market in 2023 and still generates interest capital. In 2024, SABIC, a global diversified chemicals company, announced the official opening of its new USD170 million ULTEM resin manufacturing facility in Singapore, and the first advanced specialty chemical manufacturing plant in the region that produces the high-performance thermoplastic, ULTEM resin. The new plant is a strategic interest to accommodate the target of SABIC to step up its worldwide production of the ULTEM specialty resins by over 50 percent to keep up with the upsurge in demand of the high-tech industry and production types in Asia and the Pacific, including Japan and China.
