Light Stabilizer Sunuvin 770

Share to:

Chemical Name : Bis (2,2,6,6-tetramethyl-4-piperidyl) sebacate 

Molecular formula : C28H50N2O4-2.

Molecular Weight : 480.74

CAS Number :52829-07-9

EINECS Number : 258-207-9

 Features / Benefits:

Sunuvin 770 is a low molecular weight hindered amine light stabilizer that provides excellent light stability for thick sections and films in the recommended substrates. Benefits of using Sunuvin 770 is the high light-stabilizing performance, particularly in PP thick sections. It has broad compatibility and can be easily dispersed. Compared to conventional UV-absorbers, the effectiveness of Sunuvin 770 is less dependent on the polymer’s thickness. For this reason the use of LS 770 also provides good light stability in articles with higher specific surface, e.g. films and tapes.


Sunuvin 770 is recommended to be used in polypropylene, impact modified PP (TPO), EPDM,polystyrene,

impact poystyrene, ABS, SAN, ASA and polyurethanes and is also effective in polyamides and polyacetals.

Handling & Safety:

In accordance with good industrial practice, handle with care and unnecessary personal contact. Avoid

contact with eyes. Avoid release to the environment. Avoid dust formation and ignition sources.
