Properties and USES: antioxidant st-1098 is an excellent anti-extraction, low-volatile hindered phenolic antioxidant with good thermal stability. Good compatibility, no initial coloring, no pollution, resistance to extraction. For polyamide resin, its oxidation resistance and thermal stability are better than universal antioxidant 1010, and it is safe and non-toxic. It is mainly used in polymers such as polyamide, polyolefin, polystyrene, ABS resin, acetal resin, polyurethane and rubber, etc. It can also be used in combination with auxiliary antioxidant containing phosphorus to improve the oxidation resistance.
Packaging and storage: stable, no special storage requirements, avoid high temperature and moisture during storage. Packed in plastic bags lined with cardboard boxes (drums), net weight 25kg.
Recommended dosage: 0.1-0.5%.
