Applications
From EV cooling plates to foldable-display support films and aerospace cable wrapping — PI film proves itself in real structures.
New Energy Vehicles
For EV cooling plates and FPC sensing protection: dielectric strength, heat resistance, high shear and pull-out strength, electrolyte resistance — plus battery wrapping and thermal management.
Consumer Electronics
Core material for flexible displays, 5G and wearables. Foldable modules need ultra-low CTE and high modulus; transparent PI serves transparent circuits and panels; MPI handles 10–15 GHz.
Electrical, Aerospace & Nuclear
High-end electrical insulation, aerospace and nuclear. Aviation composite film wraps conductors, replacing DuPont Oasis; corrosion-resistant composite film serves nuclear and oil-field motors.
Solar & Energy Storage
Solar and storage substrates. Deep yellow PI serves battery wrapping and solar backsheets with low shrinkage; ultra-thin film is used in screen printing and current collectors.
LED & PCB
LED board substrates. Uni- and bi-axially drawn matte black films serve as black cover film for LED strips, balancing light shielding and heat resistance.
