High-performance secondary antioxidant based on dilauryl thiodipropionate (DSTP) chemistry.
Excellent hydrolytic stability and low volatility, ensuring long-term effectiveness in high-temperature processing.
Synergistic with primary antioxidants (e.g., hindered phenols) for enhanced oxidative stability in polymer systems.
Low color contribution and minimal odor, supporting use in demanding applications including food-contact and medical-grade polymers.
Consistent batch-to-batch quality and regulatory compliance aligned with major global standards (e.g., FDA 21 CFR §178.2010, EU Directive 10/2011).
Polyolefins (PP, HDPE, LDPE) for injection molding, blow molding, and extrusion.
Thermoplastic elastomers (TPEs) requiring thermal stability during compounding and fabrication.
Cable compounds and insulation materials exposed to elevated service temperatures.
Food packaging films and containers where regulatory compliance and low extractables are critical.
Automotive interior components subject to long-term heat aging and UV exposure.
