Description

Irganox 3052 is a high-performance, multifunctional phenolic antioxidant widely recognized for its superior stabilizing effects in demanding polymer applications. Its primary value lies in its ability to effectively inhibit thermal and oxidative degradation, thereby significantly extending the service life and maintaining the physical properties of sensitive materials. This additive is essential for manufacturers in the plastics, synthetic fiber, and elastomer industries who require robust stabilization solutions for high-temperature processing and long-term durability.

Application

• Primary antioxidant for the stabilization of polypropylene (PP) and polyethylene (PE) against thermo-oxidative degradation during processing and in end-use.
• Critical additive in engineering plastics such as polyamide (PA) and polyester (PBT, PET) to prevent molecular weight loss and yellowing.
• Effective stabilizer for synthetic fibers and yarns, enhancing their resistance to heat and light exposure.
• Used in adhesives, sealants, and elastomers to maintain elasticity and prevent premature aging.
• Formulation component in lubricants and greases to inhibit oxidation and sludge formation.
• Provides synergistic effects when combined with other additives like phosphites or thioesters in polymer stabilization packages.

Quality Control

Every batch of Irganox 3052 is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure it meets precise specifications for purity and performance. Our quality assurance protocol includes verification against industry benchmarks to guarantee consistency and reliability. A Certificate of Analysis (COA) detailing specific test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture.
