Antioxidant 565

Product Overview

Antioxidant 565 represents a class of high molecular weight multifunctional phenolic antioxidants engineered for superior stabilization in demanding polymer matrices. As a non-staining additive, it provides exceptional protection against thermal oxidation during processing and long-term service life. Its unique chemical structure ensures low volatility, preventing loss during high-temperature extrusion or molding processes. This product is specifically designed for manufacturers seeking reliable performance in unsaturated elastomers and various thermoplastic applications.

Our facility produces this stabilizer under strict quality control measures, ensuring consistent batch-to-batch reliability. The high purity profile minimizes impurities that could affect the color or physical properties of the final polymer product. Whether used in rubber compounding or adhesive formulations, Antioxidant 565 delivers consistent oxidative stability. The molecule functions by scavenging free radicals generated during thermal stress, thereby interrupting the degradation chain reaction.

Technical Specifications

Industrial Applications

This antioxidant is primarily utilized as a post-polymerization process stabilizer for unsaturated elastomers. It demonstrates high efficacy in polybutadiene (BR), polyisoprene (IR), and emulsion styrene-butadiene rubber (SBR). Additionally, it is highly compatible with nitrile rubber (NBR) and carboxylated SBR latex (XSBR). Beyond elastomers, the chemical serves as a critical stabilizer for styrenic block copolymers such as SBS and SIS, ensuring durability in footwear and asphalt modification applications.

The versatility of Antioxidant 565 extends into the adhesive industry, where it protects both hot-melt and solvent-based formulations from degradation. It is also suitable for use in EPDM, ABS, high-impact polystyrene, polyamides, and polyolefins. Its low staining characteristic makes it ideal for light-colored or transparent polymer products where aesthetic quality is paramount. Common end-use products include automotive seals, industrial hoses, protective tapes, and high-performance bonding agents.
