Use:
This product is a high molecular weight UV absorber of the hydroxypheny benzotriazole class, showing outstanding light stability to a variety of polymers during its use.
It is highly effective for polymers usually processed at high temperatures such as polycarbonate, polyesters, polyacetal, polyamides, polyphenylene sulfide, polyphenylene oxide, aromatic copolymers, thermoplastic polyurethane and polyurethane fibers, where loss of UVA is not tolerated as well as for polyvinylchloride, styrene homo- and copolymers.
