Bright 100 is a high molecular weight optical brightener (fluorescent whitening agent) of the thiophenediyl benzoxazole class, suitable for the optical brightening of polymers at all stages of processing.
LS-2020 is a high molecular weight hindered amine light stabilizer (HALS). It shows excellent polymer compatibility and high extraction resistance. One of the unique features of LS-2020 is a very narrow molecular weight distribution, resulting in a consistent performance in use and processing. LS-2020 combines the typical benefits of a variety of high molecular weight HALS. It provides superior light/thermal stability to polymers and improved ancillary properties like improved polymer processing.
UV-234 is a high molecular weight ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class, imparting good light stability to a variety of polymers.
