Features Of SI Group AT-10 Antioxidant

  1. High-performance hindered phenolic antioxidant offering excellent thermal and oxidative stability.

  2. Low volatility and superior compatibility with a broad range of polymers including polyolefins and engineering thermoplastics.

  3. Effective at low dosage levels (0.05–0.3 wt%), delivering cost-efficient stabilization without compromising processing or end-product properties.

  4. Non-staining and low-color formation, supporting clarity and color fidelity in sensitive applications such as food-contact packaging and medical-grade resins.

  5. Compliant with major global regulatory frameworks including FDA 21 CFR §178.2010 and EU Regulation (EC) No 10/2011 for plastic food contact materials.

Typical Applications Of SI Group AT-10 Antioxidant

  1. Polypropylene (PP) and polyethylene (PE) fibers, films, and injection-molded parts exposed to elevated processing temperatures.

  2. Automotive interior components requiring long-term thermo-oxidative resistance under under-hood conditions.

  3. Medical device housings and tubing made from sterilizable polyolefin compounds.

  4. Food packaging films and containers where regulatory compliance and organoleptic neutrality are critical.

  5. Recycled polyolefin formulations needing robust stabilization against reprocessing-induced degradation.
