Chromium Foil (Light Tight) is a thin chromium metal foil that’s available in 3 thicknesses, ranging from 25 to 75 microns, to suit different industrial needs. This foil features high tensile strength, hardness, corrosion resistance and reflectivity. It’s also light tight, so blocks visible light transmission for sensitive applications. Chromium Foil (Light Tight) is used in the solar energy industry as a reflective layer and in chemistry as a catalyst.
