Light Stabilizer 119

Product Overview

Light Stabilizer 119, identified by CAS number 106990-43-6, represents an advanced class of non-polymeric high molecular weight hindered amine light stabilizers (HALS). Designed for demanding industrial applications, this compound offers superior protection against UV-induced degradation in a wide variety of polymer matrices. Unlike conventional stabilizers, Light Stabilizer 119 is engineered to maintain the aesthetic integrity of colored polyolefin products, preventing discoloration and ensuring long-term visual appeal. Its unique macromolecular structure provides exceptional resistance to volatility and migration, making it an ideal choice for high-temperature processing environments where material loss must be minimized.

Beyond its primary function as a UV absorber, this chemical acts as an effective antioxidant. It significantly enhances the long-term thermal stability of polyolefins, extending the service life of finished goods exposed to harsh environmental conditions. Manufacturers seeking reliable performance in outdoor applications will find this stabilizer to be a critical component in their formulation strategy. The product is supplied as light yellow particles, ensuring easy handling and dispersion during the compounding process.

Key Performance Advantages

Our Light Stabilizer 119 delivers distinct technical benefits that outperform standard alternatives in the market. The high molecular weight structure ensures that the additive remains within the polymer matrix throughout the product lifecycle. This reduces the risk of surface blooming or extraction by water and solvents. Key advantages include:

• Exceptional low volatility even at elevated processing temperatures.
• Superior migration resistance for long-lasting protection.
• Enhanced chromaticity retention for colored polyolefin applications.
• Dual functionality as both a light stabilizer and thermal antioxidant.
• Compatibility with weakly acidic environments.

Technical Specifications

Quality consistency is paramount in chemical manufacturing. Each batch of Light Stabilizer 119 undergoes rigorous testing to meet strict physical and chemical standards. The following table outlines the typical properties expected from our production lines:

Industrial Applications

Due to its versatile compatibility, Light Stabilizer 119 is suitable for a broad spectrum of thermoplastic materials. It is particularly effective in polyolefin systems such as polypropylene (PP) and polyethylene (PE). Additionally, it performs well in thermoplastic elastomers, polystyrene (PS), and styrenic materials. The stabilizer is also recommended for use in both soft and rigid PVC, polyurethane (PU), polyamide (PA), polyoxymethylene (POM), and polyesters like PET and PBT. Its high transmittance values make it suitable for applications where optical clarity is required, such as in PMMA components.

Packaging and Storage

To ensure product integrity upon delivery, Light Stabilizer 119 is packaged in 25KG cartons or paper drums. Proper storage is essential to maintain performance characteristics. The product should be stored in a dry and ventilated warehouse, protected from direct sunlight and moisture. Containers must remain sealed when not in use. As a non-dangerous good, it can be transported according to standard chemical logistics regulations. We recommend keeping the material away from fire sources and maintaining a cool environment to prevent agglomeration.
