Description

Antioxidant G-16 (Most Toxic Antiox) is a specialized phenolic antioxidant designed for high-performance stabilization in demanding industrial environments. Its primary value lies in its exceptional efficacy at low concentrations, providing superior protection against oxidative degradation and thermal aging for sensitive materials. This product is essential for industries requiring robust antioxidant solutions for polymers, synthetic lubricants, and other hydrocarbon-based systems where long-term stability is critical. CAS No. 61373-87-3.

Application

• Primary antioxidant for high-temperature processing of engineering plastics and technical polymers.
• Stabilizer for synthetic lubricants, greases, and industrial fluids to extend service life and prevent sludge formation.
• Additive in rubber and elastomer compounds to inhibit thermo-oxidative degradation during curing and in final products.
• Protective agent for adhesives, sealants, and coatings to maintain performance properties under oxidative stress.
• Stabilization component in hydrocarbon-based fuels and specialty chemical intermediates.
• Used in the formulation of antioxidant masterbatches for concentrated, easy-dispersion applications in polymer compounding.

Quality Control

Our Antioxidant G-16 is manufactured under a strict quality management system to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical testing, including assay, melting point, and color determination, to meet defined technical specifications. A Certificate of Analysis (COA) documenting all critical quality parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its nature as an easily oxidized compound, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening to maintain maximum potency. Keep away from strong oxidizing agents.
