Antioxidants

Based on 1745 products - Last update on the Jun 26, 2025

Antioxidants are characterized by their ability to prevent oxidative degradation. They function by neutralizing free radicals, which can cause the breakdown of polymer chains, leading to loss of mechanical properties and discoloration. Key features of antioxidants include enhanced durability, improved thermal stability, and preservation of physical properties. Used in packaging, automotive parts, and electronic components. 

Alternatives to antioxidants include UV stabilizers. Current trend includes the development of multifunctional antioxidants that combine radical scavenging and peroxide decomposing capabilities for comprehensive protection. Sub-types include primary antioxidants (e.g., hindered phenols) and secondary antioxidants (e.g., phosphites and thioesters).
