Light Stabilizer 2020

Product Overview

Light Stabilizer 2020, identified by CAS number 192268-64-7, represents a class of advanced polymeric hindered amine light stabilizers (HALS) engineered for demanding polymer processing environments. As a high molecular weight additive, this compound offers exceptional resistance to extraction and volatility, making it a superior choice for long-term material preservation. Our manufacturing process ensures high purity levels, typically exceeding 99 percent, which guarantees consistent performance across large-scale industrial batches. This stabilizer functions by scavenging free radicals generated during UV exposure, thereby interrupting the degradation cycle that leads to cracking, chalking, and loss of mechanical integrity in plastic substrates.

Key Features And Benefits

• Exceptional resin compatibility with polyolefins including polypropylene and polyethylene.
• Low migration and low precipitation characteristics ensure long-lasting protection.
• Superior extraction resistance suitable for items exposed to liquids or harsh environments.
• Minimal color interference preserves the aesthetic quality of pigmented products.
• Enhances long-term thermal stability during processing and end-use applications.
• Approved for use in food packaging materials in specific regulatory jurisdictions.

Technical Specifications

Industrial Applications

This stabilizer is extensively utilized in the stabilization of polyolefins such as PP and PE, as well as olefin copolymers like EVA. It is particularly effective in thin-section applications including films, fibers, and narrow tapes where low volatility is critical to prevent fogging or surface blooming. In thick-section products, it provides robust protection against deep-layer UV degradation. The additive is also highly recommended for carbon black filled systems and filled polypropylene articles where thermal stability is paramount. Due to its polymeric nature, it remains embedded within the polymer matrix, offering sustained protection throughout the product lifecycle without leaching out. This makes it ideal for automotive components, agricultural films, and outdoor construction materials that require extended weatherability.

Storage And Handling

Light Stabilizer 2020 exhibits excellent storage stability under recommended conditions. To maintain optimal quality, the material should be stored in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Avoid exposure to high humidity to prevent clumping or moisture absorption. Standard industrial safety protocols should be followed during handling, including the use of appropriate personal protective equipment. The product is typically packaged in 25kg cartons or drums to facilitate safe transportation and logistics management for global supply chains.
