Chroma Color’s alternative recipes allow the MRF sorting operations to identify and successfully sort the plastic articles according to the APR NIR Sorting Potential of a Whole Plastic Article. The leading third-party independent lab P.T.I. of Holland, Ohio, conducted all testing and analysis.
Chroma Color’s NIR Sortable Black Technology is based upon IR reflecting/transparent components using a proprietary combination of specialty dyes and organic pigments. The Chroma Color path to success allows for expanded exploration of additional Black options, including near-Black and other Dark Color families.
