For procurement managers in the plastics, textiles, and coatings industries, sourcing high-quality chemical additives is a critical task that directly impacts product performance and market competitiveness. Hindered Amine Light Stabilizer 3529 (CAS 193098-40-7), a prominent member of the HALS family, is a key component for ensuring the longevity and durability of materials exposed to UV radiation. This article, written from the perspective of a direct manufacturer, aims to guide purchasing professionals on the benefits and considerations when procuring HALS 3529.

Understanding HALS 3529: What Buyers Need to Know

Hindered Amine Light Stabilizer 3529 is a high molecular weight, oligomeric HALS designed to provide robust protection against UV degradation and thermal oxidation. Its mechanism of action involves scavenging free radicals, thereby interrupting the photo-oxidative degradation chain reaction within polymers. Key attributes that make it a sought-after additive include:

  • Exceptional Long-Term Protection: Its efficient radical scavenging provides superior, long-lasting UV stability, crucial for products with extended outdoor service requirements.
  • Low Volatility and Migration: The high molecular weight minimizes loss during high-temperature processing and reduces migration in the final product, ensuring consistent performance and safety.
  • Minimal Color Impact: HALS 3529 offers very low initial color and minimal color development upon exposure, preserving the aesthetic integrity of formulations.
  • Broad Compatibility: It is compatible with a wide range of polymers, including polyolefins (PE, PP), PVC, engineering plastics (POM, PA, PET), and ABS, and works synergistically with other stabilizers.

Procurement Strategies: Why Buy Direct from a China Manufacturer?
