Chemical name: alpha-Alkenes(C20 C24) maleic anhydride-4-amino-2,2,6,6- tetramethylpiperidine, polymer CAS No.: 152261-33-1 Molecular formula:� (C35H66N8O2) n Molecular weight: 3000-4000 Molecular structure Specification Appearance: Yellowish solid Melting point, degree: 95-125 Loss on drying,%: 0.8 max. TGA (290 degree),%: 10 max. Application LIGHT STABILIZER LS-5050H is 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. It 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 can be used in all polyolefins. It is particularly suitable for water-cooled tape production, films containing PPA and TiO2 and agricultural applications. It can also be used in PVC, PA and TPU as well as in ABS and PET.
