PRODUCT FEATURES AND APPLICATIONS
* UV5050His a high molecular weight, oligomeric hindered amine light stabilizer (HALS). 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.
UV 5050H 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.
