Application Note: Color Measurement Of Plastic Pellets Using HunterLab Instruments

In the plastics industry, the color of plastic pellets is often measured before the pellets are extruded, or molded, into a final product. Plastic pellets are typically translucent and nonuniform in size. Therefore, special accessories and presentation techniques are required to provide repeatable results. This Applications Note is designed to describe the preferred methods of measuring plastic pellets using the various HunterLab instruments.
