Applications:
It is a kind of high-effective asymmetric phenolic antioxidant, and its special features involves high efficient antioxidation, low volatility, resistance
to oxidation coloring, significant synergistic effect with assistant antioxidant (such as monothioester and phosphite ester), and giving products good
weathering resistance when used with light stabilizers. It is mainly used as process and long-time stabilizer for styrene polymer like HIPS, ABS, MBS, and
engineering thermoplastics like POM and PA, while it also serves as end stopper of chain in PVC polymerization. In addition, the product has no effect on
polymer reactions. When used for HIPS and PVC, it can be added into monomers before polymerization
Storage:
Stable in property. No special requirement but keep ventilation and away from water and high temperature.
Packing:
Cardboard boxes with plastic liners, net weight: 25kg/carton.
Recommended Dosage:
0.15-0.5%.
