High-performance secondary antioxidant based on dilauryl thiodipropionate (DLTDP) chemistry.
Excellent hydrolytic stability and low volatility, ensuring long-term effectiveness in high-temperature processing.
Synergistic with primary antioxidants (e.g., hindered phenols) to enhance overall oxidative stability.
Low color formation and minimal odor—ideal for demanding color-critical and consumer-facing polymer applications.
Compatible with polyolefins, styrenics, elastomers, and engineering thermoplastics.
Polypropylene (PP) fibers and nonwovens for medical and hygiene products.
Automotive interior components including PP and TPO trim parts.
Food-contact polyolefin packaging films and containers.
Household appliances requiring long-term thermal aging resistance.
Wire & cable insulation materials exposed to elevated service temperatures.
