The UV absorber UV-329, also known as Octrizole, is a highly effective chemical raw material widely used in numerous industries due to its exceptional properties. It provides excellent protection against the harmful effects of ultraviolet radiation.

UV-329 is a white to yellowish crystalline powder. It is characterized by its high light stability and excellent UV absorption capability, particularly in the UV-B range. Octrizole has a melting point of approximately 102-106°C and is highly soluble in many organic solvents, while it is insoluble in water. These physical properties make UV-329 an ideal UV absorber for various applications.

Application examples of UV-329

UV-329 is frequently used in the plastics industry to extend the lifespan and durability of plastic products. It protects polymers from degradation caused by UV rays, which is particularly important for outdoor applications. UV-329 is used in polyethylene, polypropylene, PVC, and other plastics to preserve their color and material stability.

In the coatings industry, Octrizole is used in paints, varnishes, and coatings. It protects coated surfaces from UV-induced damage such as cracking, discoloration, and degradation. By adding UV-329, the aesthetic and protective properties of coatings can be maintained and extended, which is particularly important for outdoor applications.

UV-329 is also used in the packaging industry to improve the durability and stability of packaging materials. It protects packaging from UV-induced damage that can lead to material degradation and color loss, thus preserving the quality of the packaged products for a longer time.

In the textile industry, UV-329 is used to protect fabrics from UV radiation. It helps preserve the colors of textiles and extend their lifespan. Octrizole can be integrated into various textile treatments to produce UV-protective clothing and other UV-resistant textile products.

UV-329 is a versatile and indispensable raw material used in numerous industries. From the plastics and coatings industries to packaging and textiles, the outstanding UV absorption properties of Octrizole offer comprehensive protection and contribute to improving the durability and quality of products. With its high light stability and broad applicability, UV-329 will continue to play a key role in various technologies and industrial processes in the future.
