What is Polyimide?

Polyimide (PI) is a unique family of ultra-high-temperature polymers containing imide linkage. PI has gained recognition for its material performance properties required for the highest demanding environments such as dimensional stability, heat resistance, chemical resistance and electrical insulation. PI can withstand extreme temperatures ranging from near -270℃ to above 400 ℃. Polyimide plays a crucial role in the electronics and aerospace industry because of its dimensional stability, electrical properties and flexibility.  By integrating advanced polyimide materials into their core, industries are accelerating into the future, crafting technology that not only meets the demands of tomorrow.
