PET Disk Metallized with Aluminum (1 Ω/sq)

PET Metallized Film with Aluminium 1 Ω/square Disk combines the mechanical strength and barrier performance of polyethylene terephthalate with a precisely deposited aluminum coating that delivers a sheet resistance of 1 ohm per square. This tailored conductivity makes it ideal for applications in sensing, circuit protection, and EMI control. Industries use these metallized disks for resistive sensor arrays, controlled-conductivity shielding layers, and flexible circuit terminations. Specific applications include sensor electrodes for environmental monitoring, static-dissipative layers in packaging for sensitive electronics, and lightweight EMI control elements in aerospace systems. In research, they support work on conductive polymer–metal composites, resistive material modeling, and optimization of thin-film deposition processes. The balance of PET’s stability and aluminum’s controlled conductivity ensures reliable integration into precision engineering and scientific projects.
