2-[2-hydroxy-3,5-di(1,1-dimethylbenzyl)phenyl]-2H-benzotriazole. Acts as a UV absorber. It is in the range of 300-400nm and has a high degree of photostability - photochemical energy absorbed in the ultraviolet region is dissipated as thermal energy. Can be used in combination with phenolic & phosphite antioxidants, and HALS to optimize performance in outdoor use. Songsorb® 2340 possesses low volatility as compared to other UVA, which makes it especially suitable for applications involving high temperature processing. Used for fibers and films, polycarbonate, POM, nylon, polyolefins, TPE, TPO.
