Introduction :

LT-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 LT-770 is less depend on the polymer's thickness. For this reason , the use of LT-770 also provides good light stability in materials with high specific surface, e.g. films and tapes. Combined with other HALS, LT-770 could perform better effectiveness, e.g. LT-791


Applications :

LT-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: 25kg carton or paper barrel(PE plastic inside)
