UV 622 can shield the ultraviolet light, reduce the transmission effect of UV light; and can also absorb high energy UV light (wavelength 290 ~ 400 m) strongly.

UV 622 is a low-dust, polymeric hindered amine light stabilizer which provides outstanding light stability to many polymers. In addition, it gives long-term heat stability to polymers by a radical trapping mechanism similar to that of hinder phenol. HALS 622 produces virtually no effect on initial substrate color. This product is a low dust white crystal, and it is suitable for those applications which demand particularly high stability for such polymers as PP, HDPE, LDPE, LLDPE, ABS and PVC.
