Key Benefits
Enhanced Thermal Stability: Protects polymers from severe degradation during film extrusion, injection molding, blow molding, and profile production.
Improved Oxidation Resistance: Primary and secondary antioxidant systems actively slow down oxidation caused by prolonged heat, oxygen contact, and extended processing cycles.
Maintained Mechanical Performance: Helps plastic products retain crucial structural properties such as tensile strength, impact resistance, flexibility, and dimensional stability.
Excellent Color Protection: Mitigates yellowing, thermal discoloration, and surface aging to maintain a consistent aesthetic appearance.
Optimized for Recycled Plastics: Counteracts prior degradation cycles in recycled polymers, significantly improving melt stability and processing consistency.
Uniform Dispersion: Advanced compounding ensures exceptional additive dispersion throughout the polymer matrix for stable, reliable performance.
Antioxidant Masterbatch Types
Primary Antioxidant Masterbatch: Neutralizes free radicals to provide long-term protection during the active service life of automotive components, outdoor infrastructure, and durable consumer goods.
Secondary Antioxidant Masterbatch: Decomposes hydroperoxides to enhance manufacturing stability and prevent thermal degradation during high-speed film extrusion, pipe production, and injection molding.
Combined Antioxidant Masterbatch: Integrates both primary and secondary systems into a single pellet, delivering dual-stage protection that combines immediate processing stability with long-term aging resistance.
Custom-Engineered Formulations: Tailored antioxidant masterbatches developed specifically for specialized resin grades, unique thermal profiles, and strict performance targets.
