AO-1425

Multifunctional phenolic primary antioxidant for processing and long-term thermal stabilization

Descrizione

AO-1425 is a phosphorous-containing high molecular weight phenolic antioxidant. It is a non-discolouring stabilizer for organic substrates such and protects these substrates against thermo-oxidative degradation. AO-1425 is odourless, light-stable and has good colour retention. It has excellent compatibility with most substrates and high resistance to extraction.
