In the plastics industry, protecting polymers from the damaging effects of ultraviolet (UV) radiation is a critical challenge. UV exposure can lead to discoloration, brittleness, and a significant loss of mechanical properties, ultimately shortening the product's lifespan. Benzophenone-3, commonly known as UV-9 or Oxybenzone (CAS 131-57-7), is a highly effective UV absorber that plays a vital role in mitigating these issues. This article explores the science behind UV-9's application in plastics and highlights why sourcing it from reliable manufacturers in China is advantageous.

UV-9 functions by absorbing UV light, typically in the range of 280-400 nm, and converting this energy into harmless thermal energy. This mechanism prevents the UV radiation from initiating photo-oxidation processes within the polymer structure, which are responsible for material degradation. Its effectiveness in a wide range of polymers, including PVC, polyesters, polystyrene, and acrylics, makes it a versatile additive for manufacturers. When purchasing, understanding the specifications, such as its appearance as a light yellow crystalline powder and its typical assay of ≥99.0%, is crucial for optimal performance.

The incorporation of UV-9 into plastic formulations significantly enhances product durability. For applications such as outdoor furniture, automotive parts, construction materials, and packaging films, resistance to UV radiation is paramount. By preventing yellowing, cracking, and loss of tensile strength, UV-9 ensures that products maintain their aesthetic appeal and structural integrity over time. Procurement managers often seek out competitive UV-9 CAS 131-57-7 price information when sourcing this additive in bulk.

For plastics manufacturers, sourcing high-quality Benzophenone-3 from a reputable Oxybenzone supplier China offers distinct advantages. These include access to large production volumes, consistent product quality, and cost-effectiveness. Establishing a relationship with a reliable manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. ensures a stable supply chain, which is critical for maintaining production schedules and meeting customer demands. We pride ourselves on being a leading manufacturer and supplier of this essential chemical intermediate.

When specifying UV-9 for plastic applications, formulators consider its compatibility with the polymer matrix, its thermal stability during processing, and its low volatility. The melting point of Benzophenone-3 (62-64°C) is generally suitable for typical plastic processing temperatures. Understanding its solubility in various organic solvents is also important for achieving uniform dispersion within the plastic. If you're asking where to purchase UV-9 powder, look for suppliers who can provide comprehensive technical support and product data sheets.

In conclusion, UV-9 (Benzophenone-3) is an indispensable additive for enhancing the UV resistance and extending the lifespan of plastic products. Its scientific efficacy, combined with the economic advantages of sourcing from Chinese manufacturers, makes it an attractive choice for the plastics industry. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing high-quality Benzophenone-3 to meet the diverse needs of polymer manufacturers, ensuring durability and performance in their end products.
