With the growing demand for weather-resistant materials in plastics, coatings, rubber, and cosmetics, UV absorbers have become essential additives in modern formulations. They effectively absorb harmful ultraviolet radiation and convert it into harmless thermal energy, preventing degradation, yellowing, and loss of mechanical properties under sunlight exposure — thereby extending the service life of end products.
UCHEM offers a comprehensive range of high-performance UV absorbers, including benzophenone types, benzotriazole types, and hydroxyphenyl-triazine types, widely used in plastics (PVC, PC, PET, PMMA), coatings, inks, rubbers, and UV-curable systems.
Main available products:
Benzophenone type: UV-P (CAS 2440-22-4), UV-531 (CAS 1843-05-6), 2-Hydroxy-4-dodecyloxybenzophenone (CAS 2985-59-3)
Benzotriazole type: UV-326 (CAS 3896-11-5), UV-327 (CAS 3864-99-1), UV-328 (CAS 25973-55-1), UV-329 (CAS 3147-75-9), UV-1 (CAS 57834-33-0), UV-360 (CAS 103597-45-1), UV-1577 (CAS 147315-50-2), UV-1164 (CAS 2725-22-6), UV-234 (CAS 70321-86-7), UV-928 (CAS 73936-91-1), UV-3030 (CAS 178671-58-4), UV-384 (CAS 127519-17-9), UV-571 / 571 (CAS 125304-04-3 / 23328-53-2), 2-(2H-Benzotriazol-2-yl)-4-methyl-6-docosylphenol (CAS 104487-30-1)
Hydroxyphenyl-triazine type: UV-400 (CAS 153519-44-9), UV-1300 (CAS 104810-48-2), UV-1130 (CAS 104810-47-1), VSU (CAS 23949-66-8)
The benzotriazole series offers excellent light stability and broad UV absorption range, making it one of the most widely used types. Meanwhile, hydroxyphenyl-triazine absorbers represent the new generation of high-efficiency UV stabilizers with outstanding thermal stability and long-term protection — ideal for engineering plastics and high-durability coatings.
Backed by a robust supply chain and strict quality management system, UCHEM ensures reliable quality, prompt delivery, and technical support. We are committed to providing efficient UV protection solutions that enhance the weatherability and market competitiveness of your materials.
