Colour Consistency & Yellowness
Colour consistency and yellowness checks help predict and control the finished appearance of parts made from recyclate.
Colour Consistency & Yellowness
Recyclate can vary in colour and develop yellowness from thermal history and contamination. Assessing colour consistency and yellowness index supports predictable appearance and effective masterbatch correction.
How we handle it, step by step
Define acceptable colour and yellowness limits.
Take representative material across the batch.
Evaluate colour consistency and yellowness.
Recommend sorting or masterbatch as needed.

Colour Consistency & Yellowness — questions we get
Why does recyclate yellow?
Thermal history, oxidation and contamination can shift recyclate toward yellow, especially in clear polymers.
Can colour be corrected?
Masterbatch and colour sorting help; darker target colours mask variation most easily.
