Polyolefins, including polypropylene (PP) and polyethylene (PE), are cornerstone materials in modern manufacturing due to their excellent mechanical properties, chemical resistance, and cost-effectiveness. However, their susceptibility to UV radiation necessitates the use of protective additives to maintain their performance over time. UV Absorber 2908 stands out as a leading solution for enhancing the durability and performance of these materials.

With its chemical identity as Hexadecyl 3,5-bis-tert-butyl-4-hydroxybenzoate and CAS number 67845-93-6, UV Absorber 2908 is classified as a benzoate-type UV absorber. Its molecular structure is optimized to efficiently absorb UV light, acting as a sacrificial shield for the polymer. The key benefits it offers include:

  • Low Volatility: This ensures that the additive remains integrated within the plastic matrix even at elevated processing temperatures, providing sustained UV protection throughout the product's lifecycle.
  • Good Solubility: Its solubility characteristics facilitate uniform dispersion in polyolefin resins, leading to consistent and effective UV protection across the entire material.
  • Excellent Compatibility: UV Absorber 2908 works harmoniously with other common polymer additives, such as Hindered Amine Light Stabilizers (HALS) and phosphite antioxidants. This compatibility allows for the creation of synergistic additive packages that deliver superior overall stabilization.
  • FDA Sanctioning: Its approval for use in polyolefins for indirect food contact applications expands its utility into sensitive product areas, making it a versatile choice for food packaging and related items.

The application of UV Absorber 2908 is critical for extending the service life of polyolefin products exposed to sunlight. This is particularly important for items like agricultural films, automotive components, outdoor signage, and construction materials. By preventing UV-induced degradation, it helps these products retain their aesthetic appeal and functional integrity.

As a dedicated plastic additive supplier, we offer UV Absorber 2908 as a high-performance solution for manufacturers looking to optimize their polyolefin formulations. Its role as a critical component in protecting against UV damage makes it an indispensable tool for ensuring product quality and longevity. The selection of appropriate additives is crucial for maximizing the benefits of polyolefins, and UV Absorber 2908 is a prime example of a product that delivers on its promise of enhanced performance and durability.
