Description

Styrenated Diphenylamine CAS NO 68442-68-2 is a high-performance antioxidant and stabilizer belonging to the diarylamine chemical class. This compound is critical for preventing oxidative degradation and extending the service life of polymers and synthetic materials under demanding conditions. It is an essential additive for manufacturers in the rubber, plastics, and lubricant industries seeking to enhance product durability and performance stability.

Application

• Primary antioxidant in synthetic rubbers (SBR, BR, NBR) and natural rubber to prevent chain scission and crosslinking.
• Stabilizer for polyolefins (e.g., polyethylene, polypropylene) and other thermoplastic polymers against thermal-oxidative degradation during processing and end-use.
• Additive in lubricating oils and greases to inhibit oxidation, control viscosity increase, and prevent sludge formation.
• Protective agent in adhesives, sealants, and elastomeric components to maintain flexibility and mechanical properties.
• Stabilizing component in fuel and industrial fluids to enhance shelf-life and operational reliability.
• Used in the production of wire and cable insulation to improve long-term thermal endurance.

Quality Control

Our Styrenated Diphenylamine is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, performance, and consistency. Certificates of Analysis (COA) documenting key parameters such as assay, color, and melting point are provided to guarantee reliable quality for your industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
