Product Technical Details

Product Overview

Light Stabilizer 3346 represents a advanced class of high molecular weight hindered amine light stabilizers (HALS) engineered to provide exceptional longevity and weatherability to polymeric materials. As a critical functional additive in the specialty chemicals sector, this compound effectively scavenges free radicals generated by UV exposure, thereby preventing photo-oxidative degradation. Its unique chemical structure ensures minimal migration and low volatility, making it an ideal choice for demanding applications where long-term stability is paramount.

Manufactured under strict quality control protocols, Light Stabilizer 3346 delivers consistent performance across various processing conditions. The product is specifically designed to maintain the mechanical integrity and aesthetic appearance of plastics exposed to harsh environmental conditions. Our commitment to excellence ensures that every batch meets rigorous international standards for purity and functionality.

Key Features And Benefits

The superior performance of Light Stabilizer 3346 is attributed to its high molecular weight architecture, which offers distinct advantages over conventional low molecular weight stabilizers. Key technical benefits include:

  • Exceptional resistance to extraction and volatility, ensuring prolonged service life.
  • Low color contribution, preserving the clarity and hue of finished products.
  • Broad compatibility with polyolefins and engineering plastics.
  • Synergistic effects when used alongside UV absorbers and other HALS variants.
  • Compliance with FDA regulations for food contact packaging materials.
  • High thermal stability suitable for high-temperature processing operations.

Industrial Applications

Light Stabilizer 3346 is versatile and widely utilized across multiple polymer processing industries. Its robust stabilization profile makes it suitable for:

  • Polyethylene (PE) films, tapes, and rotational molding sheets.
  • Polypropylene (PP) fibers, injection molding parts, and thermoplastic olefins (TPO).
  • Engineering plastics including Polyacetals, Polyamides, PET, PBT, and PUR.
  • High-performance resins such as ASA, ABS, HIPS, and PMMA.

Whether used in automotive components, agricultural films, or consumer packaging, this additive ensures that materials retain their strength and appearance over extended periods of UV exposure.

Storage And Handling

To maintain optimal quality, containers should be kept tightly closed in a cool, dry environment. Avoid exposure to direct sunlight and moisture during storage. The standard packaging configuration is a 25KG carton box, designed for safe global transportation.
