Yihoo AN445 is a sterically hindered phenolic antioxidant specifically designed for organic polymers. It effectively protects materials against thermal oxidative degradation during production, processing, and end-use stages. Notably, Yihoo AN445 demonstrates exceptional efficacy in styrenic polymers—particularly HIPS, ABS, MBS, SB, SBR latex, as well as POM homopolymers and copolymers. It is also suitable as a stabilizer for polyurethanes, polyamides, thermoplastic polyesters, PVC, and other polymer systems. This product features odorless properties, low volatility, excellent color fastness, and high anti-extraction performance. It exhibits good compatibility with other additives, such as secondary antioxidants (e.g., thioethers, phosphites), light stabilizers, and antistatic agents. |
