UV Absorber 531
UV Absorber 531 is a highly effective ultraviolet light absorber of the benzophenone class, offering exceptional protection against UV-induced degradation for a wide range of polymers and coatings. Its key function is to absorb harmful UV radiation between 240-340 nm, thereby preventing material breakdown, discoloration, and loss of physical properties.
- Low yellowing and excellent absorbance in the UV-B region contribute to the improved failure resistance of coatings, preventing discoloration, cracking, and loss of adhesion from sunlight exposure.
- This benzophenone UV absorber provides strong UV absorption and excellent polymer compatibility, making it suitable for protecting polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polystyrene (PS) products.
- The synergistic effect of UV absorber 531 when used in combination with hindered amine light stabilizers (HALS) is crucial for applications like agricultural films and thick section products, offering enhanced light stability.
- Its low volatility and resistance to migration ensure long-term effectiveness and prevent contamination during processing, making it an ideal additive for plastic manufacturing.
