Uvinul® 5050 H

Uvinul® 5050 H by BASF is a high molecular weight, oligomeric hindered amine light stabilizer (HALS). It is alpha-alkenes(C20-C24) maleic anhydride-4-amino-2,2,6,6-tetramethylpiperidine, polymer. It shows excellent polymer compatibility and good extraction resistance. It exhibits high compatibility in polyolefins resulting in low water take-up during production of tapes. Uvinul® 5050 H combines the typical benefits of a variety of high molecular weight HALS. It provides good light and thermal stability to the polymer and improved ancillary properties like low water carry-over (WCO). It offers good light stability to PE and PP tapes, PP fibers, PE films and thick articles of PP & PE. It is also suitable for olefin copolymers such as EVA, blend of polypropylene with elastomers and flexible/rigid PVC or PVC blends. The recommended dosage level is 0.1-1.4% in fibers, 0.1-0.8% in tapes, 0.05-1.0% in thick sections and 0.1-1.0% in films.
