Palladium Thin Film Sizes is a thin foil of palladium metal deposited on polyester film. This flexible metallic film exhibits high reflectivity and low resistivity. With good corrosion resistance, palladium films find use in electronics as low-loss conductors or as reflective coatings. They also serve as catalysts in chemical production and pollution control applications. The range of film thicknesses and polyester substrates available from Goodfellow allows tailoring palladium films for diverse industrial and research needs.
