Description

Antioxidant Ao80 is a high-performance phenolic antioxidant widely used to inhibit oxidative degradation and extend the service life of various polymeric materials. Its primary value lies in providing exceptional thermal stability and preventing chain scission and cross-linking during processing and end-use. This additive is essential for manufacturers in the plastics, rubber, and synthetic fiber industries seeking to enhance product durability and performance under demanding conditions.

Application

• Polyolefin Stabilization: Primary antioxidant for polypropylene (PP) and polyethylene (PE) resins to prevent thermal oxidation during extrusion, molding, and long-term aging.
• Synthetic Rubber Protection: Used in styrene-butadiene rubber (SBR), polybutadiene rubber (BR), and other elastomers to maintain elasticity and prevent cracking.
• Engineering Plastics: Stabilizer component in nylon (PA), polycarbonate (PC), and polyester (PBT, PET) formulations to ensure color stability and mechanical integrity.
• Adhesives and Sealants: Protects adhesive polymers from oxidative breakdown, preserving bond strength and flexibility.
• Thermoplastic Elastomers (TPEs): Enhances the weatherability and service life of TPE products used in automotive and consumer goods.
• Masterbatch Production: A key active ingredient in antioxidant and stabilizer concentrate masterbatches for simplified compounding.

Quality Control

Our Antioxidant Ao80 is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, melting point, and impurity profiles. Our quality protocols are designed to meet the stringent requirements of global polymer producers, with testing methodologies aligned with industry standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) after opening to maintain efficacy. Keep away from heat sources and incompatible materials.
