Leadstab AO 245 is a high-effective asymmetric phenolic antioxidant, and its special features involves high efficient antioxidation, low volatility, resistance to oxidation coloring, significant synergistic effect with secondary antioxidant (such as monothioester and phosphite ester), and giving products good weathering resistance when used with light stabilizers. Leadstab AO 245 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.
The packaging is 25kgs carton (inner with plastic bag). Other packages are available as customers' requirements.
Keep ventilation and away from water and high temperature.
