Types of antioxidants | Protective additives for thermal and optical stability of polymers<\/span><\/h2>

Supply of primary, secondary and combined antioxidants for the formulation of various polymers and masterbatches<\/span><\/h3>

Antioxidants<\/strong> are chemical additives added to polymer compounds to prevent thermal, optical, or oxidative degradation. This degradation typically occurs due to oxidation at high temperatures or exposure to oxygen and UV<\/strong> during production, storage, or end use. <\/p>

In the plastics industry, the use of antioxidants plays a key role in increasing shelf life, preserving color, preventing brittleness, and maintaining<\/strong> mechanical properties.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
