Tiangang® UV-237 is a highly efficient UV absorber for a variety of plastics and other organic substrates, including polyolefins, and most engineering plastics, as well as PVC, PMMA, PU, PET, POM, polyesters, and various elastomers (TPU, TPE), and adhesives. Tiangang UV-237 features strong UV absorption, low initial color, excellent compatibility, and moderately low volatility. When added to the substrates, it protects the substrate from UV degradation, preserving the original appearance and physical integrity of molded articles, films, sheets, and fibers during outdoor use.

Dosage level of Tiangang® UV-237 is between 0.10 and 1.0%, depending on substrate and performance requirements. When used in combination with Tiangang® series of Hindered Amine Light Stabilizers (HALS), synergistic performance is often observed.
