Our GB Conventional Polyimide Black Film is an opaque, non-transparent coverlay engineered for flexible printed circuits (FPCs) requiring structural confidentiality. With a *matte black finish (L ≤ 25)** and high-temperature resistance, it prevents visual reverse-engineering while providing electrical insulation, mechanical protection, and chemical stability—ideal for military, aerospace, and premium consumer electronics.
Military/Aerospace FPCs – Radar systems, drone controls
Medical Implantables – Pacemakers, neurostimulators
High-End Wearables – Foldable displays, smartwatch PCBs
Automotive Sensors – ADAS camera flex circuits
Industrial IoT – Anti-tamper sensor modules
