Process Introduction

Polyimide (PI): The High-Performance Polymer Engineered for Extremes

Polyimide (PI) is synthesized through precise polycondensation of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in strong polar solvents, followed by advanced casting and imidization. This exceptional engineering polymer delivers:

 

Unmatched Thermal Resilience

Continuous operation at 269°C to 280°C with peak performance up to 400°C

 

Critical Protection Properties

• Extreme temperature stability (-269°C to +400°C)

• Superior electrical insulation & dielectric strength

• Exceptional mechanical/radiation resistance

• Robust adhesion across substrates

 

Plutosemi masters both PI dry film and adhesive technologies, delivering precision-engineered solutions for mission-critical applications.
