Rapid Adoption in Additive Manufacturing

Polyetherimide (PEI) is a robust 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, also known as 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 traditional manufacturing processes would require.

PEI is an excellent recipient of a 3D print as it can withstand intense temperatures, is very durable, and is resistant to breaking. This makes it applicable in components that require a long lifespan, even under extreme conditions. To illustrate, airplane parts, car parts, and even medical tools are made using PEI.

The ease of use of 3D printing machines today, combined with their increased sophistication, is encouraging other firms to incorporate PEI into their products. It also supports faster testing of new designs, and this accelerates product development. The relatively 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.

Polyetherimide Industry Segmentation

This section provides an analysis of the key trends in each segment of the global polyetherimide market report, along with forecasts at the global, regional, and country levels for 2025-2033.

The Reinforced Segment Dominates the Polyetherimide Market

Based on grade, the polyetherimide market is segmented into Unreinforced and Reinforced. In 2024, the Reinforced segment dominated the market and is anticipated to continue its leadership throughout the forecast period. Increased application in high-performance areas like aerospace, automotive, and electronics has made the demand for reinforced PEI rather high. Such industries need the material that can resist high temperatures, mechanical load, and corrosive chemicals, which reinforced PEI is superior at. The reinforcement of PEI will expand as the industry's demand for stronger and more sustainable components increases. Additionally, the manufacturing technologies of injection molding and 3D printing have emerged due to technological breakthroughs that allow a more refined design of reinforced PEI parts with complex geometry and exposed details. This is especially useful in such industries as aerospace or automotive, where lightweight and high-performance materials are paramount. With industries seeking to make the products lighter, particularly in the automotive and aerospace sectors, to enhance fuel economy, lightweight but strong materials have increasingly become acceptable. Reinforced PEI has the strength and stability necessary in such applications and does not significantly increase the weight of a product, which is an advantage.

The Granule Category held the Largest Market Share in the Polyetherimide Market.

Based on form, the polyetherimide market is segmented into Sheet, Rod, Granule, and Film. In 2024, the granule segment held the largest share and is expected to remain at the top for the next few years. The granules are much preferred as they present ease of processing and excellence in material handling. They are widely employed in the extrusion and injection molding processes, which are part and parcel of numerous industries, e.g., automotive, aerospace, or electronics. This granule shape enables you to have a uniform and accurate control over the molding process, resulting in the manufacture of quality and reliable components. Polyetherimide granules could simply be modified and mixed with different additives to make a specific character, like high flame retardancy, high conductivity, or UV resistance. This customization capability serves to render granules suitable for use in varied industries where special properties of materials are needed. The granules are generally affordable than the other types of polyetherimide (sheets or films) in case of a large production. Their large capacity for handling and convenient storage ability make them appealing to manufacturers aiming at expanding their production without spending too much, thus making the segment enjoy a corner in the market.

Asia Pacific Dominated the Global Polyetherimide Market

Asia Pacific leads the market presently in polyetherimide, and it is also likely to dominate the market in the forecast period.  The dominance is primarily due to the large electronics and semiconductor production base in the region, the fast-growing electric-vehicle and battery manufacturing sector, and the progressive transition to lightweight, flame-resistant polymer materials in motor vehicles and aircraft parts. Large plants of PEI resin and compounders are available in China and Japan, so local cost-effective supply can be done, and at the same time, large-scale OEMs make use of material content in 5G antenna housing, high-temperature connectors, and EMI shielded modules. Government Policies like the Made in China 2025 plan, the Production-Linked Incentives (PLI) programs in India, and the investment in high‑speed rail and aircraft projects hasten the demand even more. Moreover, current PEI application businesses, such as the medical-device and food-package industries in the Asia Pacific, are mainly due to its ability to meet super strict sterilization and sanitary requirements. The miniaturization of additive-manufacturing hubs in Singapore, South Korea, and mainland China lends itself to wider adoption of PEI powder and filament for rapid prototyping and smaller manufacturing facilities. As region-based manufacturers focus more on reducing weight, thermal management, and regulatory compliance, the share of Asia-Pacific in the demand for polyetherimide is likely to override that of the rest of the regions throughout the forecast period.

China held a dominant Share of the Asia Pacific Polyetherimide Market in 2024

China has been growing as a giant in the polyetherimide market globally, supported by robust government industrial policies, technology-driven metropolises like Beijing, Shanghai, and Shenzhen, and massive investments with the assistance of government guidance funds to the efforts of the Made in China 2025 scheme.
