Features Of BASF Irganox 1098 Antioxidant

  1. High-performance hindered phenolic antioxidant specifically designed for polyamide (PA6, PA66) processing and long-term thermal stability.

  2. Excellent compatibility and low volatility in high-melting engineering thermoplastics, minimizing blooming and plate-out.

  3. Outstanding hydrolytic stability—retains efficacy even under humid processing conditions and in moisture-sensitive polymers.

  4. Synergistic with phosphite co-stabilizers (e.g., Irgafos 168), enabling optimized stabilization packages for demanding applications.

  5. Non-discoloring performance—preserves polymer clarity and color stability during extrusion, injection molding, and long-term aging.

Typical Applications Of BASF Irganox 1098 Antioxidant

  1. Stabilization of polyamide 6 (PA6) for automotive under-hood components.

  2. Long-term thermal stabilization of polyamide 66 (PA66) in electrical & electronics housings and connectors.

  3. High-temperature processing aid for glass-fiber reinforced polyamides used in structural engineering parts.

  4. Stabilizer in polyamide-based hot-melt adhesives requiring melt stability and oxidative resistance.

  5. Key additive in food-contact compliant polyamide packaging films (subject to regional regulatory approval).
