Most polymers undergo oxidative degradation during manufacturing, compounding, and processing. Heat and oxygen trigger free-radical formation, leading to polymer chain cleavage and degradation, which can cause:
- Loss of shine and transparency
- Yellowing
- Surface cracking and odours
- Reduced mechanical properties (impact resistance, tensile strength, elongation)
Anti-Oxidant Additives and Masterbatches prevent autoxidation by stabilizing polymers at the molecular level. They maintain color, mechanical properties, and overall polymer integrity during processing and long-term use. Oxidation resistance is evaluated through standards like DIN 53383, measuring viscosity changes, mechanical properties, and yellowing to assess effectiveness.
