High-efficiency secondary antioxidant based on dilauryl thiodipropionate (DSTP) chemistry.
Excellent hydrolytic stability and low volatility, ensuring long-term performance in high-temperature processing.
Synergistic with primary antioxidants (e.g., hindered phenols) to enhance overall oxidative resistance.
Low color formation and minimal odor—ideal for demanding color-critical and consumer-facing polymer applications.
Compliant with major global food-contact regulations including FDA 21 CFR §178.2010 and EU Directive 10/2011 (subject to specific migration limits).
Polyolefins (PP, HDPE, LDPE) for injection-molded automotive parts and packaging films.
Wire & cable insulation and jacketing compounds requiring thermal aging resistance.
Rotomolded polyethylene tanks and industrial containers exposed to prolonged heat and UV stress.
Food-grade plastic containers, caps, and closures where regulatory compliance and low extractables are critical.
Recycled polyolefin blends, where DSTP helps mitigate degradation during multiple extrusion cycles.
