In the competitive landscape of polymer manufacturing, extending product lifespan and maintaining material integrity are paramount. Ultraviolet (UV) radiation and thermal stress are primary culprits behind polymer degradation, leading to discoloration, loss of mechanical strength, and premature product failure. This is where advanced additives like Hindered Amine Light Stabilizers (HALS) play a critical role. Among these, Light Stabilizer 622 stands out as a highly effective solution for a wide array of polymer applications.

Light Stabilizer 622, also known by its CAS number 65447-77-0, is an oligomeric HALS. Its unique molecular structure confers low volatility and minimal migration, making it an ideal choice for applications where permanence is essential. As a premier manufacturer based in China, we understand the critical needs of businesses seeking reliable polymer additives. Our commitment is to provide high-purity Light Stabilizer 622 that addresses these challenges effectively.

Understanding the Mechanism: HALS vs. UV Absorbers

While UV absorbers work by absorbing UV radiation and dissipating it as heat, HALS function through a radical scavenging mechanism. They are catalytic and are regenerated during the stabilization process, providing long-lasting protection. Light Stabilizer 622 excels in this regard, offering superior performance, especially in pigmented systems where UV absorbers may be less effective. For businesses looking to buy Light Stabilizer 622, understanding this mechanism highlights its advantage in demanding applications.

Key Features and Benefits of Light Stabilizer 622

  • Dual Functionality: Beyond its primary role as a light stabilizer, Light Stabilizer 622 also acts as an effective antioxidant. This dual action significantly contributes to the long-term heat stability of materials like polyolefins and tackifier resins.
  • Low Migration and Volatility: Its oligomeric nature ensures it remains within the polymer matrix, reducing loss during processing and end-use, and preventing contamination of surrounding materials.
  • Excellent Performance: It surpasses many traditional UV absorbers in effectiveness, particularly when used in conjunction with pigments.
  • Synergistic Effects: When combined with other UV stabilizers, such as certain UV absorbers or other HALS compounds, Light Stabilizer 622 can exhibit synergistic effects, leading to even greater protection and extended product lifespan.

Applications Across Industries

The versatility of Light Stabilizer 622 makes it an indispensable additive for numerous industries. It is highly recommended for:

  • Polyolefins: Including polypropylene (PP) and polyethylene (PE), widely used in automotive parts, outdoor furniture, and packaging.
  • Olefin Copolymers: Such as EVA (ethylene-vinyl acetate), crucial for films, adhesives, and footwear.
  • Polyacetals and Polyamides: Offering enhanced durability for engineering plastics used in demanding mechanical applications.
  • Polyurethanes and Elastomers: Protecting flexible materials in coatings, seals, and textiles from UV-induced degradation.
