Antioxidant PEP-36

Product Overview

Antioxidant PEP-36 represents a class of advanced phosphite stabilizers designed to significantly enhance the longevity and processing characteristics of modern polymers. Registered under CAS 80693-00-1, this compound is chemically identified as Bis(2,6-di-ter-butyl-4-methylphenyl)pentaerythritol-diphosphite. It is specifically engineered to provide exceptional protection against thermal degradation during high-temperature manufacturing processes such as extrusion and molding. Unlike conventional stabilizers, PEP-36 offers superior resistance to hydrolysis, ensuring consistent performance even in challenging environmental conditions where moisture might compromise lesser additives. This makes it an ideal choice for manufacturers seeking reliability, efficiency, and extended product life in their production lines.

Key Performance Features

Our premium grade Antioxidant PEP-36 delivers multiple technical advantages that optimize polymer integrity and final product quality. The unique molecular structure allows for significant synergistic effects when combined with primary phenolic antioxidants, maximizing the protective potential of your entire formulation system. Key benefits include exceptional thermal stability during processing, marked resistance to hydrolysis which prevents premature degradation, and effective prevention of discoloration or yellowing in finished goods. Furthermore, it helps maintain melt flow rate stability under high heat, ensuring consistent viscosity. Importantly, this material is compliant with indirect food contact regulations in the US, EU, and Japan, making it highly suitable for sensitive packaging applications.

Technical Specifications

Quality control is paramount in our manufacturing process. Each batch undergoes rigorous testing to ensure it meets strict international standards for purity and performance. The following table outlines the critical physical and chemical parameters guaranteed for every shipment:

Industrial Applications

Due to its versatile stability profile, Antioxidant PEP-36 is widely utilized across various sectors of the plastics and resin industry. It is particularly effective in polyolefins such as polypropylene (PP) and high-density polyethylene (HDPE). Furthermore, it performs excellently in styrene resins including polystyrene (PS) and ABS. Engineering plastics such as polyamides (PA), polycarbonates (PC), and polyesters also benefit from its addition to prevent thermal oxidation. Given its regulatory approval, it is highly suitable for food packaging applications where safety and stability are critical. Our sales team can provide detailed compatibility charts for specific polymer matrices upon request.

Handling And Storage

To maintain optimal quality, containers should remain tightly closed when not in use to prevent moisture absorption. The product must be stored in a cool, dry environment away from direct moisture and heat sources. Proper handling ensures that the chemical properties remain intact until the point of incorporation into your manufacturing process. We offer bulk packaging options, typically 20kg cartons, to suit large-scale industrial requirements and ensure cost-effective logistics for global partners.
