TECHNICAL INFORMATION Color Changes in Polyolefins – Pinking

Pinking, yellowing, discoloring, and gas fading are different names that describe color changes in polyethylene. These color changes are generally associated with the over-oxidation of the phenolic antioxidant that is added to the resin to protect and stabilize it during processing and use. The condition is strictly cosmetic and does not adversely
