UCHEM specializes in supplying high-quality UV absorbers and light stabilizers for plastics, coatings, rubber, and industrial materials. Our UV absorbers are designed to protect polymers from UV radiation, preventing yellowing, degradation, and loss of mechanical strength caused by sunlight exposure. By integrating UCHEM is UV stabilizers into your formulation, you can significantly enhance weatherability, color stability, and long-term durability of finished products.
We provide a complete range of benzophenone-type, benzotriazole-type, and hydroxyphenyl-triazine-type UV absorbers, suitable for applications in PVC, PET, PC, PMMA, PU coatings, adhesives, inks, and elastomers.
