Improved UV wear resistance

Petition / Problem

Improve the ultraviolet resistance of a plastic that fades after being exposed to the sun for a few hours.

Objective

Understand why this discoloration occurs, propose a solution and verify that it improves resistance until reaching customer quality standards.

ATRIA solution

After characterizing the failure, it was observed that the problem was in the additive that protected the base polymer . New additives with better performance were selected and prototype parts were manufactured with them.

Finally, quality tests were carried out and the additive that met all customer specifications was selected.
