Polyimide (PI) Film Series
Polyimide (PI) Films
Polyimide (PI), one of the world’s most advanced super engineering polymers, is referred to as the “golden film.” PI stands out due to its superior heat resistance, mechanical strength, electrical insulation, chemical stability, and flexibility. As one of three fundamental engineering polymers, alongside carbon and aramid fibers, high-performance PI film plays a pivotal role in modern high-tech industry development. Thanks to its high-purity formulation, low shrinkage rate, and excellent processability, PI film is a preferred material for a wide range of industrial and electronic applications requiring high performance.
PI film is used in flexible electronics, 5G communication systems, next-generation display technologies, thermal management solutions, aerospace, and high-temperature insulation.
Polyimide (PI) Products
Electrical Insulation Group
PI films developed for electrical applications are designed to be reliable, especially under harsh voltage conditions. These films’ standout feature is their superior corona resistance, which makes them ideal insulation materials for high-voltage motors and cables.
HN Series - General Electrical Insulation PI Film
This is a general-purpose, Class C insulating material used in electrical and electronic industries.
HCR / FCR Series - Corona-Resistant PI Film
The HCR/FCR Series of polyimide films is designed for use in high-voltage insulation applications, such as in train traction motors, wind turbines, and electric vehicle systems.
- Their corona-resistant structure provides superior resistance to electrical discharges and maintains insulation performance in environments exposed to continuous voltage stress. Additionally, the films’ high chemical stability and heat resistance ensure reliable, long-lasting performance in harsh industrial conditions.
- The films’ high surface purity and dimensional homogeneity make them suitable for precision insulation structures, and their flexible structure is compatible with various winding and lamination types.
Applications:
- Electrical insulation material for traction motors in high-speed trains.
- It is also a thermoplastic (fluorine-free) insulation composite film for electromagnetic wires, cables, etc.
