Features Of ADEKA ADK STAB TPP Antioxidants

  1. Highly effective phosphite-based secondary antioxidant for hydroperoxide decomposition.

  2. Excellent thermal stability during high-temperature polymer processing (e.g., extrusion, injection molding).

  3. Low volatility and minimal migration, ensuring long-term stabilization in finished products.

  4. Compatible with a broad range of primary antioxidants (e.g., hindered phenols) for synergistic performance.

  5. Non-staining and color-stable—ideal for applications requiring high optical clarity and low yellowness development.

Typical Applications Of ADEKA ADK STAB TPP Antioxidants

  1. Polyolefins (PP, HDPE, LDPE) for automotive interior parts and packaging films.

  2. Engineering plastics including polyamide (PA6, PA66) and PBT used in electrical connectors and under-hood components.

  3. Thermoplastic elastomers (TPEs) and thermoplastic vulcanizates (TPVs) requiring consistent mechanical retention.

  4. Recycled polyolefin streams where enhanced melt stability and reprocessing resistance are critical.

  5. Food-contact compliant plastic containers and closures meeting FDA 21 CFR §178.2010 requirements.
