Engineering plastics are prized for their superior mechanical properties, durability, and performance in demanding applications. However, even these robust materials are not immune to the effects of oxidation and thermal degradation, which can compromise their integrity during processing and throughout their service life. To combat this, manufacturers rely on high-performance additives, and Composite Antioxidant B225 stands out as a crucial component for enhancing the longevity and stability of engineering plastics.

Composite Antioxidant B225 is a synergistically formulated blend, typically combining a hindered phenolic antioxidant (like Antioxidant 1010) with a phosphite antioxidant (like Antioxidant 168). This dual-action approach provides comprehensive protection. The phenolic component scavenges reactive free radicals generated by heat and shear, while the phosphite component decomposes hydroperoxides, preventing the propagation of oxidative damage. This combination is particularly vital for engineering plastics, which often undergo more rigorous processing conditions and are expected to perform reliably in challenging environments.

The advantages of using Composite Antioxidant B225 in engineering plastics are significant. It offers excellent melt stability, ensuring that resins maintain their intended viscosity and flow characteristics during high-temperature processing methods like injection molding and extrusion. This prevents issues such as excessive degradation, gel formation, and discolouration, which can lead to rejected parts and increased manufacturing costs. Furthermore, it imparts excellent long-term thermal stability (LTTS), enabling the finished plastic components to withstand prolonged exposure to heat without significant loss of mechanical strength, toughness, or dimensional stability. This is a key consideration for engineers designing parts for automotive, aerospace, and electronic applications.
