In the chemical industry, particularly in polymer formulation, precise application and optimal dosage of additives are critical for achieving desired performance characteristics. For professionals working with UV protection, understanding the effective use of UV Absorber UV-327 (CAS 3864-99-1) is paramount. This guide, curated for procurement managers and R&D scientists, provides insights into the recommended dosages and application methods for UV Absorber UV-327, drawing on the expertise of leading manufacturers and suppliers.

UV Absorber UV-327 is a highly efficient benzotriazole-based UV absorber that offers excellent protection against UV-induced degradation in a variety of polymers. Its efficacy is directly tied to its concentration within the polymer matrix. While exact requirements can vary based on the specific polymer, processing conditions, and intended application lifespan, general guidelines from manufacturers provide a solid starting point.

For polyolefins such as polyethylene (PE) and polypropylene (PP), typical recommended dosages for UV Absorber UV-327 range from 0.2% to 0.6% by weight. This range allows formulators to tailor the level of protection based on the product's exposure conditions – higher concentrations are typically used for materials intended for prolonged outdoor use. For manufacturers working with polyvinyl chloride (PVC), dosages are generally between 0.2% and 0.5%. Similarly, for ABS resins, the recommended range is often 0.3% to 0.5%.

The application of UV Absorber UV-327 is typically straightforward, often incorporated during the compounding or extrusion stages of polymer processing. Its good compatibility with polyolefins and other resins ensures it disperses evenly within the melt, providing uniform protection throughout the final product. For those looking to buy in bulk, understanding these application nuances helps in planning production and ensuring consistent quality.

When considering procurement, it's essential to partner with a supplier that provides not only high-purity UV Absorber UV-327 but also technical support regarding dosage optimization.
