Antioxidant 225

Antioxidant 225 is a mixed stabilizer that improves polymer processing and increases the long-term thermal stability of resins. Antioxidant 225 is prepared by mixing the main antioxidant 1010 (hindered phenol) and the auxiliary antioxidant 168 organic phosphite in a ratio of 1:1. Antioxidant 225 helps to maintain the fluidity of the resin, prevent color change, and improve the thermal stability of polyolefin and olefin copolymers such as polyethylene, polypropylene and polybutene.
