Ningbo Inno Pharmchem Co.,Ltd is a leading manufacturer of 2-(2-Hydroxy-5-tert-octylphenyl)benzotriazole, also known as UV-329, a highly effective ultraviolet light absorber. This product has become increasingly popular due to its excellent performance in protecting various materials against UV radiation.

UV-329 is a benzotriazole type ultraviolet absorber with a molecular weight of 323.43, and it is widely used in plastics, coatings, adhesives, and other materials that require protection from UV radiation. It is a white or slightly yellowish powder with a melting point of 120-125°C.

The synthetic route used by Ningbo Inno Pharmchem Co.,Ltd to produce UV-329 is highly efficient and environmentally friendly. The process begins with the reaction of 2-(2-hydroxy-5-tert-octylphenyl)benzotriazole with 1,1,3,3-tetramethylbutylamine under specific conditions to produce UV-329. This method is designed to minimize waste and maximize the yield of the final product, resulting in a high-quality UV absorber that meets the strictest industry standards.

One of the main advantages of UV-329 is its ability to offer long-lasting protection against UV radiation. It has excellent light stability, which means it can effectively absorb UV radiation and prevent the degradation of materials over time. This makes it ideal for use in outdoor applications, as well as products that are exposed to UV radiation for extended periods.

In addition, UV-329 is highly compatible with a wide range of materials, including polyolefins, PVC, polycarbonate, acrylics, and polyesters. It is also suitable for use in food contact applications and complies with FDA regulations. Furthermore, it is non-toxic, non-corrosive, and does not have any adverse effects on the environment.

Ningbo Inno Pharmchem Co.,Ltd is a reliable supplier of high-quality UV-329. With advanced production equipment and strict quality control procedures, the company ensures that each batch of UV-329 meets the highest quality standards. The product is packaged in 25kg bags or according to customer requirements and delivered promptly to customers around the world.

UV-329 is a highly competitive product in the market, and it competes with other well-known UV absorbers such as BASF light stabilizer Tinuvin 329, also known as BASF Tinuvin 329, and Cytec Light Stabilizer CYASORB UV-5411, also known as American Cytec UV-5411 or Cyasorb UV-5411. However, UV-329 has several advantages over these products, including its lower cost, better compatibility with a wider range of materials, and higher stability under extreme conditions.

In summary, UV-329, also known as Oxytriazole, 2-[2-Hydroxy-5-(1,1,3,3-tetramethylbutyl)phenyl]benzotriazole, 2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol, or Octrizole, is a highly effective ultraviolet light absorber that offers long-lasting protection against UV radiation. It is widely used in various industries, including plastics, coatings, adhesives, and food contact applications. Ningbo Inno Pharmchem Co.,Ltd is a trusted manufacturer and supplier of high-quality UV-329, and its synthetic route and quality control procedures ensure that each batch of the product meets the strictest industry standards. With its excellent performance and competitive pricing, UV-329 is an excellent choice for anyone looking for a reliable and cost-effective UV absorber.
