Polyimide Film (Xenomax®)

High-performance polyimide film for flexible electronics and next-generation displays.
Delivers unmatched thermal and dimensional stability for demanding optical and sensor applications.

Dimensionally Stable Polyimide Film for Advanced Display and Sensor Technologies

Xenomax® is an advanced polyimide film developed by Xenomax Japan Co., Ltd., a joint venture of TOYOBO CO., LTD. and NAGASE & CO., LTD. This high-performance material is specifically designed for applications requiring ultra-low thermal expansion, exceptional flatness, and optical transparency – such as flexible displays, fingerprint sensors, and electronic paper.

Thanks to its unique molecular orientation process, Xenomax® achieves extremely low coefficients of thermal expansion (CTE), making it ideal for substrates in optoelectronics where alignment and dimensional accuracy are critical.

NAGASE supplies Xenomax® polyimide film globally for applications in flexible electronics, next-generation displays, and advanced sensor modules – with full technical and logistics support.
