Antioxidant JY-245

Antioxidant JY-245 by Beijing Jiyi Chemicals is ethylene bis (oxyethylene) bis[ß-(3-tert-butyl-4-hydroxy-5-methylphenyl) propionate] or triethylene glycol bisß-(3-tert-butyl-4-hydroxy-5-methylphenyl) propionate. Acts as high-effective asymmetric phenolic antioxidant. Offers highly efficient antioxidation, low volatility, resistance to oxidation coloring, significant synergistic effect with assistant antioxidant (such as mono thioester and phosphite ester) and giving products good weathering resistance when used with light stabilizers. Is mainly used as process and long-time stabilizer for styrene polymer like HIPS, ABS, MBS, as well as engineering thermoplastics like POM and PA, while it also serves as end stopper of chain in PVC polymerization. In addition, the Antioxidant JY-245 has no effect on polymer reactions. When used for HIPS and PVC, it can be added into monomers before polymerization.
