Molecular Weight 225 g/mol
Description Tiangang® UV-P is an efficient UV absorber for a variety of plastics and other organic substrates, including polyolefins, and engineering plastics, as well as PVC, PMMA, PU, PET, POM, polyesters, and various elastomers, and adhesives, especially those with lower processing temperatures. 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-P is between 0.10 and 0.5%, depending on substrate and performance requirements. When used in combination with Tiangang® series of Hindered Amine Light Stabilizers (HALS), synergistic performance is often observed.
