This product is a sulfur-containing macromolecular antioxidant with low volatility, good heat resistance, and low extractability.

It is particularly suitable for polyolefins and engineering plastics to extend heat resistance and long-term aging resistance.

When used together with hindered phenolic antioxidants, it offers better stability than other thioether antioxidants.

It provides color protection and is commonly used in polypropylene (PP), polyethylene (PE), ABS, polystyrene (PS), and other engineering plastics, especially in thin-wall and film applications requiring low volatility.
