  YCPS-770 is a low molecular weight hindered amine light stabilizer(HALS) that provides excellent light stability for thick sections、films and tapes in the recommended substrates , particularly in PP thick sections. It has broad compatibility and can be easily dispersed.
  
  Compared to conventional UV-absorbers , the effectiveness of YCPS-770 is less depend on the polymer’s thickness. For this reason , the use of YCPS-770 also provides good light stability in materials with high specific surface, e.g. films and tapes.Combined with other HALS,
  
  Application: YCPS-770 is recommended to be used in polypropylene , impact modified PP(TPO) , EPDM , polystyrene , impact polystyrene,ABS,SAN,ASA and polyurethanes and is also effective in polyamides and polyacetal.
  Package and Storage: 25kg carton or paper barrel(PE plastic inside)
