Highly effective sulfur-based co-stabilizer for synergistic performance with primary antioxidants such as hindered phenols.
Excellent processing stability during high-temperature extrusion and injection molding of polyolefins.
Low volatility and minimal plate-out tendency, supporting clean production and consistent part quality.
Compatible with common polymer additives including acid scavengers, UV absorbers, and nucleating agents.
Contributes to long-term thermal oxidative stability in demanding end-use environments.
Polypropylene (PP) fibers and nonwovens for hygiene and medical applications.
Automotive interior and under-hood polyolefin components exposed to elevated temperatures.
Food-contact compliant PP and HDPE packaging films and containers.
Thin-walled PP injection-molded parts requiring high melt stability and low odor.
