Applications                                        
 
UV 2020 is a higly effective light stabilizer for polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.
 
In addition, in certain instances UV 2020 is highly effective in poly- acetals, polyamides, polyurethanes, flexible and rigid PVC, as well as PVC blends and in certain styrenic elastomer and specialty adhesive applications.
