Highly effective sulphur-based co-stabilizer for synergistic performance with primary antioxidants (e.g., hindered phenols).
Excellent processing stability during high-temperature extrusion and compounding of polyolefins.
Low volatility and minimal plate-out, supporting clean operation in continuous production lines.
Compatible with common polymer additives including acid scavengers, UV absorbers, and other HALS stabilizers.
Contributes to long-term thermal oxidative stability in demanding end-use environments.
Polypropylene (PP) homopolymers and copolymers for automotive interior parts.
High-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) for pipes and pressure vessels.
Thermoformed packaging films requiring enhanced melt stability and clarity retention.
Nonwoven fabrics used in hygiene and medical applications where thermal processing robustness is critical.
