UV Absorber UV-P

Product Overview

UV Absorber UV-P, chemically identified as 2-(2'-Hydroxy-5'-methylphenyl)benzotriazole, stands as a premier solution in the realm of polymer stabilization. This high-efficiency ultraviolet absorber is engineered to protect synthetic materials from the detrimental effects of solar radiation. By effectively absorbing UV light within the critical 270 to 380 nanometer wavelength range, it prevents photo-oxidative degradation that commonly leads to surface cracking, yellowing, and mechanical failure in plastic products. Our manufacturing process ensures a purity level exceeding 99%, making this product a reliable and cost-effective alternative to established industry benchmarks such as BASF Tinuvin P.

Designed for versatility, UV-P exhibits excellent compatibility with a broad spectrum of resin systems. Its chemical structure provides superior thermal stability, allowing it to withstand high-temperature processing conditions without significant decomposition or volatilization. This characteristic is particularly vital for engineering plastics like polycarbonate that require processing at elevated temperatures. Furthermore, the compound is odorless and demonstrates minimal absorption of visible light, ensuring that the final products maintain their desired clarity and color integrity.

Technical Specifications

Industrial Applications

The application scope of UV Absorber UV-P extends across multiple sectors of the plastics and coatings industry. It is extensively utilized in the stabilization of polyvinyl chloride (PVC), polystyrene (PS), polycarbonate (PC), and polymethyl methacrylate (PMMA). Additionally, it performs exceptionally well in AS resin, ABS resin, polypropylene (PP), and polyethylene (PE) formulations. For specialized applications involving polyester, epoxy cellulose acetate, and polyacrylonitrile resins, this absorber provides robust protection against weathering and UV-induced aging.

Due to its optical properties, UV-P is especially recommended for colorless, transparent, and light-colored products where aesthetic quality is paramount. The recommended dosage is flexible depending on the specific application requirements and product thickness. For thin films and sheets, a concentration of 0.1% to 0.5% is typically sufficient. For thicker molded products, the dosage can be optimized between 0.05% and 0.2%. This adaptability allows formulators to achieve the desired balance between performance and cost efficiency.
