Light Stabilizer 2908

Product Overview

Light Stabilizer 2908 represents a premium class of hindered phenol antioxidants specifically engineered to enhance the longevity and structural integrity of polymer matrices. Chemically known as Hexadecyl 3,5-Bis-Tert-Butyl-4-Hydroxybenzoate, this compound functions as a highly effective radical scavenger that mitigates the degradation caused by ultraviolet radiation and thermal stress. Our manufacturing process ensures exceptional purity levels, making it an ideal choice for demanding industrial applications where material failure is not an option.

As a specialized additive, this stabilizer exhibits remarkable compatibility with polyolefin substrates, including polypropylene and polyethylene systems. Unlike conventional stabilizers, it maintains low volatility even under elevated processing temperatures, ensuring that the protective benefits remain within the polymer matrix throughout the product lifecycle. This retention capability is crucial for maintaining mechanical properties and aesthetic appearance over extended periods of exposure to harsh environmental conditions.

Technical Specifications

Industrial Applications

The versatility of Light Stabilizer 2908 allows for broad deployment across multiple sectors within the plastics and rubber industries. It is particularly effective in protecting colored opaque substances such as pipes, storage tanks, plates, and various plastic garden articles from UV-induced aging. The chemical structure provides robust protection against gas fade and maintains stability in basic environments, which is essential for outdoor construction materials and automotive components.

• Superior protection in polypropylene (PP) and flame retardant polyolefin systems.
• Excellent synergy when combined with benzophenone UV stabilizers or phosphite antioxidants.
• Non-discoloring properties ensure the final product retains its intended aesthetic quality.
• Extraction resistant formulation suitable for items exposed to water or chemicals.

Storage and Handling

To maintain optimal quality and performance characteristics, proper storage protocols must be followed. Containers should remain tightly closed to prevent moisture absorption and contamination. The material should be stored in a cool, dry place away from direct sunlight and heat sources. Our company provides comprehensive Material Safety Data Sheets (MSDS) and Certificates of Analysis (COA) with every shipment to ensure compliance with global safety standards and regulatory requirements. As a global manufacturer, we support bulk pricing structures and offer technical formulation guides to assist engineers in integrating this stabilizer into their specific production lines.
