Conductive PI

Electromagnetic shielding material

Conductive PI (polyimide) film is a common conductive film material, mostly used in the electronics industry, as the foam or silicone gasket wrapping layer to provide EMI shielding and grounding effects. Its main components are polyimide (PI) and plated metal, generally, nickel-plated (silver gray), gold-plated (gold), tin-plated (silver), copper-plated (purplish red), etc. The thickness is 0.016mm or 0.025mm.
