Antioxidants for Polyurethane Application

Polyurethanes, like other organic materials, react with oxygen in a process call “autoxidation.” This degradation process results in discoloration and loss of physical properties of products.

UHS-629 is an effective anti-yellowing stabilizing system that provides long-term heat stability by preventing thermo-oxidative degradation during processing and service life. It is suitable to applied in many polymers like TPU , PUR , rubbers or other plastics.
