For procurement managers and R&D scientists in the chemical and materials industries, securing a consistent supply of high-quality additives is critical for product development and manufacturing success. Ultraviolet (UV) absorbers, like UV Absorber 531 (Octabenzone, CAS 1843-05-6), play a vital role in protecting materials from UV degradation. This guide is designed to help buyers navigate the process of sourcing this essential compound, particularly from China, a major global supplier.

UV Absorber 531 is a highly effective benzophenone-based UV light absorber. Its primary function is to protect polymers such as polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polycarbonate (PC) from the damaging effects of sunlight. Without this protection, materials can become brittle, discolored, and lose their essential physical properties. UV Absorber 531 works by absorbing UV radiation and converting it into heat, thereby preventing damage to the polymer matrix.

When considering purchasing UV Absorber 531 from Chinese manufacturers, it's essential to prioritize quality and reliability. Look for suppliers who can provide detailed technical data sheets (TDS), Certificates of Analysis (COA), and Material Safety Data Sheets (MSDS). These documents confirm the purity and specifications of the product, ensuring it meets your application requirements. As a reputable manufacturer and supplier, we are committed to transparency and provide comprehensive documentation for our UV Absorber 531.

The price of UV Absorber 531 can vary depending on purity, order volume, and supplier. Buyers should aim for competitive pricing without compromising on quality. Understanding market rates and obtaining multiple quotes can help secure the best value. Factors influencing price include raw material costs, production efficiency, and logistical expenses. By partnering with an established supplier, you can benefit from economies of scale and a stable price structure.

Key considerations when sourcing UV Absorber 531 from China include:

  • Supplier Reputation: Verify the supplier's track record, certifications (e.g., ISO), and customer reviews.
  • Product Quality: Ensure high purity (typically ≥99%) and consistent batch-to-batch quality.
  • Logistics: Confirm packaging standards (e.g., 25kg drums) and reliable shipping options to your location.
  • Technical Support: A good supplier will offer technical assistance and readily answer your queries.

UV Absorber 531 finds extensive application in plastics, coatings, and rubber industries, enhancing product durability and appearance. Whether you are developing new formulations or optimizing existing ones, ensuring a dependable supply of this critical additive is paramount.
