Description Tiangang® UV-326 is a UV absorber suitable for a variety of plastics and other organic substrates, especially polyolefins, and cold cured polyesters. It has a wide range of indirect food approvals in polyolefins. It features strong UV absorption, and 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-326 is between 0.10 and 0.50%, depending on substrate and performance requirements. When used in combination with Tiangang® series of Hindered Amine Light Stabilizers (HALS), synergistic performance is often observed.
