High-efficiency secondary antioxidant based on dilauryl thiodipropionate (DLTDP) chemistry, optimized for thermal and oxidative stability.
Excellent compatibility with polyolefins including PP, HDPE, and LDPE without blooming or migration issues.
Low volatility and superior extraction resistance in hot-water and detergent environments.
Synergistic performance when combined with primary antioxidants such as hindered phenols (e.g., BHT, Irganox 1010).
Non-staining, non-discoloring formulation suitable for color-critical applications.
Polypropylene (PP) fibers and nonwovens for medical and hygiene products.
HDPE blow-molded containers for food and chemical packaging.
Automotive interior components exposed to elevated under-hood temperatures.
Rotomolded tanks and industrial piping systems requiring long-term UV/thermal resistance.
Cable jacketing compounds in low-smoke, zero-halogen (LSZH) formulations.
