Features Of Addivant ALKANOX 240 Antioxidant

  1. High-performance phosphite antioxidant offering exceptional melt stability for polyolefins during high-temperature processing.

  2. Excellent hydrolytic stability, minimizing degradation in humid or aqueous environments during storage and compounding.

  3. Low volatility ensures long-term retention in finished products, supporting extended service life under thermal stress.

  4. Synergistic with hindered phenols (e.g., Irganox 1010), enabling optimized antioxidant package performance at reduced loading levels.

  5. Non-staining and low odor—ideal for applications requiring aesthetic and sensory integrity, including packaging and consumer goods.

Typical Applications Of Addivant ALKANOX 240 Antioxidant

  1. Polypropylene (PP) fibers and nonwovens used in geotextiles, filtration media, and hygiene products.

  2. High-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) blow-molded containers and pipes.

  3. Automotive interior components, including PP-based dashboards, trim, and under-hood parts exposed to elevated temperatures.

  4. Food-contact compliant polyolefin packaging films and rigid containers meeting FDA and EU regulatory requirements.

  5. Recycled polyolefin formulations where enhanced stabilization is required to counteract accumulated oxidative damage.
