Automatic plastic sorting systems in recycling plants work with NIR sensors that do not always correctly identify certain colorants such as conventional silver shades. With NIR Silver, ECKART has developed a pigment solution that is tailored to the needs of automatic sorting.

NIR spectroscopy uses the wavelength signature of specific polymers to distinguish between them. NIR Silver optimally reflects these specific wavelengths and thus supports the sorting of plastics.

The pigments are easy to process in all conventional plastics and provide impressive silver metallic effects. Particularly in combination with post consumer resins, NIR Silver offers the packaging industry an interesting opportunity to further strengthen its efforts with regard to sustainability.

With NIR Silver, ECKART provides the industry with another pigment solution on how to best reduce its environmental footprint – an additional building block in the growing sustainability portfolio of the effect pigment manufacturer.
