The global colorless polyimide film market is projected to generate USD 6,174.2 million revenue by 2030, advancing at a CAGR of 70.1% during 2024–2030. This can be ascribed to the rising demand for flexible display panels, which propels the usage of flexible optoelectronics. In addition to this, with the rising popularity of smartphones, tablets, iPads, and other electronic products with flexible displays that can be folded or rolled, the market will continue to advance.
Colorless polyimide films are known for their optical clarity and transparency. Polyimide is a high-performance polymer that is valued for its thermal stability, mechanical strength, and electrical insulating properties. These sheets are designed to be nearly transparent, allowing them to transmit light with minimal distortion. Moreover, they are flexible and can be bent, folded, or shaped, without losing their optical properties.
Flexible displays receive great attention due to their lightweight nature, thin packaging, impact resistance, and lack of a spatial limit of use compared with conventional glass-based displays. A key drive for the market is the smartphone industry, which has been steadily growing across the world. According to Ericsson, globally, 6.92 billion people on earth owned a smartphone in 2023, which means that 85% of the population owns one. Therefore, smartphones and tablets have a major impact on the demand for flexible displays.
Moreover, foldable smartphones are gaining attention due to their compactness and foldability, despite a larger screen size when unfolded. Apart from these gadgets, flexible displays are ideal for wearable electronics, such as fitness trackers and smartwatches, as they can be worn around the wrist or wrapped around other body parts. Furthermore, devices with foldable displays are significantly lightweight and small, especially when then components are incorporated into mid-size and large electronic devices, such as tablets and laptops with screens larger than 10 inches.
However, the launch of polyimide films made of flexible substrates has enlarged their application in flexible AMOLED displays, allowing hard glass with flexible substrates to be replaced and making displays lighter, thinner, and less fragmented. Moreover, such transparent polyimide films are a key component of solar cells due to their stability in processing temperatures as high as 3,000 °C, which, in turn, enhances the power conversion efficiency of solar cells.
The electronic sector held the largest market share in 2023, as these sheets provide excellent thermomechanical properties, strong chemical resistance, and high optical transparency. These properties make them popular for manufacturing electronic components, such as flexible printed circuit boards and flexible displays for mobile phones and other devices. Moreover, several colorless polyimide film plants have been operating in South Korea since 2021; CPI is expected to be used in the new generation of foldable mobile phones.
Geographically, the Asia-Pacific region is expected to grow with a CAGR of about 72% during the forecast period. This is owing to the growing economies, the rising number of manufacturing plants, the increasing foreign investments, the availability of cheap labor, and the surging use of transparent polyimide film across various industries and applications, for example, smartphones.
The major players operating in the colorless polyimide film market include DuPont de Nemours Inc., KANEKA CORPORATION, KOLON Industries, Dr. Dietrich Müller GmbH, NeXolve Holding Company LLC, I.S.T Corporation, Wuxi Shunxuan New Materials Co. Ltd., Zymergen Inc., and Suzhou Kinyu Electronic Technology Co. Ltd.
