Antioxidant 1520

Product Overview

Antioxidant 1520 represents a advanced solution in the realm of polymer stabilization, specifically engineered to protect organic substrates against thermo-oxidative degradation. This high-efficiency liquid additive functions as a primary antioxidant, combining hindered phenol chemistry with thioether synergists to deliver exceptional performance during both processing and long-term heat aging. Its unique molecular structure ensures low volatility and superior stability under light and heat exposure, making it an indispensable component for manufacturers seeking to extend the service life of rubber and plastic products.

As a non-staining and non-discoloring agent, Antioxidant 1520 is particularly valued in applications where aesthetic integrity is paramount. The product maintains clarity and color consistency even under rigorous thermal conditions, ensuring that the final manufactured goods meet strict quality standards. Furthermore, its regulatory compliance across multiple jurisdictions, including the USA, EU, China, and Japan, facilitates its use in food contact applications, broadening its utility across packaging and consumer goods sectors.

Technical Specifications

Applications and Benefits

The versatility of Antioxidant 1520 allows it to be seamlessly integrated into a wide array of polymer matrices. It is highly compatible with thermoplastic elastomers and various rubber types, including BR, SBR, NBR, IR, SBS, SIS, and natural rubber. In the adhesives and sealants industry, it provides critical protection for solvent-based and water-based systems, as well as styrene copolymers and polyurethane dispersions. The recommended dosage level typically ranges from 0.05% to 0.3%, offering cost-effective stabilization without compromising material properties.

• Superior thermal oxidation resistance during high-temperature processing.
• Excellent compatibility with diverse elastomers and thermoplastic systems.
• Non-staining formulation ensures product aesthetic quality.
• Global regulatory approval for indirect food contact applications.
• Low volatility reduces loss during extended heat aging.

Storage and Handling

To maintain optimal quality and performance, Antioxidant 1520 should be stored in tightly closed containers within a cool, dry environment. Protection from moisture and direct sunlight is recommended to prevent any potential degradation prior to use. The standard packaging configuration consists of 200kg drums, designed for safe global transportation and handling. Our company adheres to strict quality control protocols, ensuring every batch is accompanied by a Certificate of Analysis (COA) to verify compliance with specified physical and chemical characteristics.
