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-4050 is a low molecular weight hindered amine light stabilizer (HALS) for thermoplastics and elastomers, in particular for applications demanding high light stability (e.g. styrenic polymers and PP). It provides excellent light stability for articles with a high surface area such as films and tapes, as it’s not dependent on the polymer’s thickness.
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.
