Background
As a globally renowned leader in advanced materials and high-tech manufacturing, Hanwha is committed to developing next-generation flexible displays and cutting-edge electronic devices. The project required polyimide films with outstanding heat resistance, dimensional stability, and electrical insulation properties to meet the demanding requirements of flexible OLED display substrates and high-frequency circuit boards.

• High-Performance Material Requirements: The polyimide films needed to maintain stable mechanical properties and an extremely low coefficient of thermal expansion under high-temperature processing conditions.

• Technical Consistency: Ensuring uniformity, reliability, and reproducibility in mass production posed significant challenges.

• Sustainability: Materials had to comply with stringent environmental regulations while supporting green manufacturing and sustainable product lifecycle management.

• High-Temperature Resistant Polyimide Film
  Using advanced synthesis and casting technology, the film demonstrates long-term stability at temperatures exceeding 400°C, with a thermal expansion coefficient below 10 ppm/°C. It fully meets the performance requirements for flexible displays and advanced semiconductor packaging.

• Superior Mechanical and Electrical Properties
  The film offers high tensile strength, low dielectric constant, and minimal dielectric loss, making it an ideal material for high-frequency circuit applications.

• Mass Production and Quality Assurance
  Fully automated production lines and a rigorous quality control system ensure batch-to-batch consistency, high production yields, and reliable performance.

• Environmental Sustainability
  All products comply with international environmental standards such as RoHS and REACH. Certain product series incorporate bio-based or green monomers, supporting Hanwha's sustainability initiatives.
