Product Application

Antioxidant 245 is a highly efficient asymmetric hindered phenol antioxidant. Its outstanding features are high antioxidant efficiency and low volatility. It has low toxicity, good oxidation resistance and coloring resistance, and has a significant synergistic effect with auxiliary antioxidants (such as thioesters or phosphites). Used together with light stabilizers, it can give products excellent weather resistance. Mainly used in the processing and long-term heat stabilizer of styrene polymers such as HIPS, ABS, MBS and engineering thermoplastic resins such as POM and PA. It is also an effective chain terminator in the PVC polymerization process. In addition, this product has no effect on polymer reactants. When used in high-impact polystyrene and polyvinyl chloride, it can be added to the monomer before polymerization. The general dosage is 0.05%-1.0%.

Reference dosage

According to different application fields, the recommended amount of antioxidant 245 is as follows:

Styrene polymer (HIPS, ABS, MBS, etc.): 0.05% ~ 0.5%;

Polyacetal, thermoplastic polyurethane, etc.: 0.1%～0.5%;

Chain terminator for PVC polymerization: 0.1%～0.5%.
