For professionals in the chemical, plastics, and coatings industries, understanding the role and benefits of UV absorbers is key to developing high-performance, long-lasting products. UV Absorber 531, with CAS number 1843-05-6, stands out as a highly efficient and versatile solution for combating UV degradation. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in manufacturing and supplying this critical additive, ensuring quality and reliability for our global clientele.

UV Absorber 531 belongs to the benzophenone class of UV absorbers, renowned for their effectiveness in protecting materials from the damaging effects of ultraviolet radiation. Its primary function is to absorb UV light within a specific spectrum (240-340 nm) and dissipate it as harmless thermal energy. This process significantly retards the photo-oxidative degradation that can plague polymers and coatings, leading to discoloration, chalking, loss of gloss, and reduced mechanical strength. If you are looking to buy UV Absorber 531, our company is a top-tier manufacturer in China.

The product's physical characteristics are noteworthy: it appears as a slightly yellow powder. Key technical advantages include its low volatility, which ensures it remains within the polymer matrix during processing, and excellent resistance to migration, meaning it won't leach out over time. These properties contribute to its sustained efficacy in protecting the material. Its compatibility with various polymer systems, including PE, PP, PVC, PS, PC, and EVA, as well as its suitability for high-solid coatings, makes it an exceptionally versatile additive.

The applications for UV Absorber 531 are broad and impactful. In plastics, it's integral to extending the lifespan of products exposed to sunlight, from agricultural films to automotive components. In coatings, it protects finishes in automotive paints, industrial applications, and decorative surfaces, maintaining aesthetic appeal and integrity. Rubber products also benefit significantly from its UV protection, preventing premature aging and failure. We are a trusted supplier for these diverse industrial needs.

For optimal performance, UV Absorber 531 often works in synergy with other stabilizers, such as antioxidants and Hindered Amine Light Stabilizers (HALS). This combination provides a comprehensive defense mechanism against various degradation pathways, including photo-oxidation and free-radical attack. When seeking to purchase UV Absorber 531, consulting with our technical team can help you determine the most effective stabilization package for your specific application.
