Features Of Songwon SONGNOX DSTDP Antioxidant

  1. High-efficiency secondary antioxidant based on dilauryl thiodipropionate (DSTDP) for synergistic stabilization with primary phenolic antioxidants.

  2. Excellent hydrolytic stability and low volatility, ensuring long-term performance in high-temperature processing conditions.

  3. Superior compatibility with polyolefins including polyethylene (PE) and polypropylene (PP), minimizing bloom and migration issues.

  4. Non-staining and non-discoloring—ideal for applications requiring color fidelity and clarity.

  5. Low odor profile and compliant with major food-contact regulations (e.g., FDA 21 CFR §178.2010, EU Directive 10/2011).

Typical Applications Of Songwon SONGNOX DSTDP Antioxidant

  1. Polyolefin films and packaging (e.g., shrink film, heavy-duty sacks, food-grade laminates).

  2. Injection-molded and blow-molded polypropylene automotive components (bumpers, interior trims, battery cases).

  3. Rotomolded polyethylene tanks and containers for chemical storage and water treatment.

  4. Wire & cable insulation and jacketing compounds requiring thermal and oxidative stability.

  5. Medical-grade polyolefin tubing and disposable devices where low extractables and regulatory compliance are critical.
