Description

Antioxidant3114 CAS NO 27676-62-6 is a high-performance, hindered phenolic antioxidant widely recognized for its exceptional stabilizing effects in polymeric materials. Its primary value lies in effectively inhibiting thermal and oxidative degradation, thereby significantly extending the service life and maintaining the physical properties of finished products. This additive is essential for manufacturers across the plastics, rubber, and synthetic fiber industries who require reliable protection against polymer aging under demanding conditions.

Application

• Primary antioxidant for polypropylene (PP) and polyethylene (PE) resins.
• Stabilizer for engineering plastics such as polyamide (PA) and polycarbonate (PC).
• Protective additive in synthetic rubbers and elastomers to prevent cracking and loss of elasticity.
• Used in adhesives and sealants to enhance shelf-life and performance stability.
• Stabilizing component in fiber and filament production.
• Additive for hot melt adhesives and polymer-based coatings.
• Can be used in food-contact compliant polymer formulations (subject to specific regulatory approval and grade).
• Effective in lubricants and greases to prevent oxidative thickening.

Quality Control

Our production of Antioxidant3114 adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for assay and purity, to ensure it meets precise specifications. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with every shipment. We support compliance with global regulatory frameworks, including REACH, and can supply grades suitable for specific industry standards 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). This product is hygroscopic (moisture-sensitive) and should be kept under dry conditions to prevent caking and performance loss. Keep away from strong oxidizing agents.
