Antioxidant 697 with CAS No. 70331-94-1 is a hindered phenolic antioxidant supplied as a powder or pellet for industrial compounding. Its chemical structure, 2,2-oxamidobis[ethyl 3-(3,5-di-t-butyl-4-hydroxyphenyl) propionate], delivers long-term thermal stability to polymer and rubber formulations. This grade is specifically designed to inhibit oxidative degradation in wire and cable insulation, automotive parts, and industrial rubber goods, extending service life under high-temperature conditions.
The additive is non-staining and compatible with polyolefins, elastomers, and engineering thermoplastics, where it maintains mechanical properties during processing and end-use. Typical industry use includes stabilising polypropylene, polyethylene, and EPDM compounds, with standard loadings between 0.1 and 0.5 percent by weight. Its low volatility and high extraction resistance make it suitable for outdoor applications exposed to UV and ozone.
Manufacturers in the automotive, electrical, and construction sectors source this antioxidant for bulk compounding, where it prevents embrittlement and surface cracking. Bulk supply is common in 25 kg paper bags or 500 kg big bags, with storage recommended in a cool, dry environment below 30 degrees Celsius. Buyers should confirm packaging and handling protocols to avoid moisture absorption, which can reduce effectiveness.

Before placing an order, verify that the CAS number and chemical structure match your formulation requirements. Request a Certificate of Analysis to confirm purity levels and absence of contaminants, as these directly impact performance in polymer applications. Ensure the supplier provides batch-specific data for consistency.
Discuss logistics details such as Incoterms, with FOB Guangzhou being a common choice for this origin. Clarify lead times, which can vary based on production schedules and bulk order sizes. Payment terms like L/C or T/T should be negotiated upfront, along with any applicable export documentation for customs clearance.
Conduct quality checks upon receipt, including visual inspection for colour consistency and particle size distribution. Request test reports for key parameters like melting point and solubility. For critical applications, arrange third-party laboratory testing to validate performance against your specifications.
