Lanxess Challenge: Reducing Discoloration of Polyamides Exposed to Air and High Temperatures challenge

Discoloration of Polyamides

The Seeker produces various formulated materials based on polyamide 6 and polyamide 66 that are used for technical applications in temperature ranges above 150°C. Over time (after a few weeks), it is observed that the material’s original light color darkens towards a brownish black, and the Seeker’s studies suggest that such discoloration is due to oxidative processes at elevated temperatures. The Seeker has attempted to solve this problem by testing a number of commercially available additives in its formulation (anti-oxidants, etc.) but none was successful.

Hence, the Seeker is challenging Solvers to propose novel ideas for an additive or combination of additive products that can be used to stabilize its products. More details can be found in the Detailed Description section of the Challenge.
