The battle against material degradation caused by ultraviolet (UV) radiation is a constant concern for polymer manufacturers. While UV absorbers are essential for protecting plastics, their effectiveness can be significantly compromised if they are lost during the manufacturing process, particularly during high-temperature processing. This is where the critical attribute of “low volatility” comes into play, making low volatility UV absorbers indispensable for durable polymer formulations.

At NINGBO INNO PHARMCHEM CO.,LTD., we recognize the necessity of high-performance additives that can withstand challenging processing conditions. UV Absorber 234 (CAS 70321-86-7) exemplifies this, offering exceptional UV protection with the advantage of low volatility. As a dedicated UV absorber supplier, we aim to provide solutions that enhance the longevity and performance of your polymer products.

Why is Low Volatility Crucial?

Many polymers, especially engineering plastics like polycarbonates, polyesters, and polyamides, are processed at temperatures well above 200°C. During these high-temperature stages, conventional UV absorbers with high vapor pressures can:

  • Evaporate: Leading to a significant reduction in the concentration of the UV absorber in the final product.
  • Cause Processing Issues: Volatilized additives can lead to equipment fouling, surface defects, and undesirable emissions.
  • Reduce Long-Term Efficacy: The material's protection against UV radiation diminishes prematurely, leading to accelerated degradation and reduced product lifespan.

Low volatility UV absorbers, such as UV Absorber 234, are specifically engineered with higher molecular weights and lower vapor pressures. This ensures they remain physically incorporated within the polymer matrix throughout the entire processing cycle and subsequent service life of the product.

UV Absorber 234: A Solution for Durability

UV Absorber 234, a hydroxyphenyl benzotriazole derivative, offers a robust solution:

  • High Thermal Stability: It resists degradation and volatilization at elevated processing temperatures.
  • Efficient UV Filtering: It strongly absorbs UV radiation, protecting the polymer from photo-oxidative breakdown.
  • Versatile Application: It is highly effective in polycarbonates, polyesters, polyacetals, polyamides, PVC, and styrenic copolymers, as well as in films and fibers.
  • Synergistic Potential: It works well in combination with other stabilizers like HALS and antioxidants for enhanced protection against weathering.
