Antioxidant 24
Why don't plastic chairs suddenly crumble after sitting in the sun? Why doesn't a food container become brittle after being molded at temperatures above 200°C?
The answer often isn't the plastic itself.

It's the tiny amount of additives hidden inside.

During manufacturing, plastics are exposed to intense heat and oxygen. Without protection, their long molecular chains begin to break apart through oxidation. The result is familiar: yellowing, cracking, loss of strength, and eventually failure.

Antioxidant 24 is one of the quiet molecular ""bodyguards"" developed to stop that process. Instead of becoming part of the plastic structure, it intercepts unstable oxidation products before they can trigger a destructive chain reaction. Working together with other stabilizers, it helps polymers survive manufacturing and remain durable for years.
