How to measure the color of Virgin Plastic Pellets?
How do you get repeatable color measurements from virgin plastic pellets when the pellets themselves don't form a flat, uniform surface?
Whether opaque, transparent, or translucent, differences in pellet geometry, orientation, optical properties, and surface characteristics can influence color readings. Objective color measurement helps manufacturers verify production against established standards and catch lot-to-lot color shifts earlier. That's where Agera L2 helps.
Its reference grade, 0°/45° circumferential geometry reduces directional effects, while its large port plate and extra large area of view measure more pellets with each reading, minimizing the effect of how individual pellets are positioned in the cup.
Grade A CIE D65 with controlled UV provides consistent conditions for color evaluation. Standardize Agera L2 according to the recommended procedure.
Then measure your physical standard to establish the color reference for comparison. Fill a clean glass sample cup so the material completely covers the measurement area. The built-in camera lets you confirm sample positioning before measurement.
Put the opaque cover on and take a reading. Dump and refill with fresh pellets two more times. The average of the three readings is one measurement result. With an area of view 4 to 16 times larger than competitors, Agera L2 delivers superior repeatability, even when the same material is refilled
and measured multiple times.
Now compare the sample with your standard. L*, a* star, and b* star quantify color, while ΔE shows the overall color difference. Yellowness Index and Whiteness Index provide additional color information.
With reliable color data, manufacturers can compare lots and catch color shifts before the resin moves into molding, extrusion, or other conversion
processes, helping reduce waste, reprocessing, and downstream quality issues.
