Detailed Description

intro:
 

Low Molecular Weight Hindered Amine Light Stabilizer (HALS)

 


Characterization 
YS 770 is a hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surfacearea such as films and tapes.

 

Chemical Name Bis (2,2,6,6-tetramethyl-4-piperidyl) sebaceate
CAS Number 52829-07-9
Structure YS 770

 

 
 
 
 
Molecular Weight 480.74
 
Applications YS 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.
 
Features/Benefits YS 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 YS 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 YS 770 is less dependent on the polymer’s thickness. For this reason the use of YS 770 also provides good light stability in articles with higher specific surface, e.g.films and tapes.
Combined with other HALS YS770 is part of other synergistic blends, e.g. YS 791

Guidelines for use
   The recommended concentrations range between 0.1% and 0.5%, depending on the substrate, processing conditions and application.  The optimum level is substrate and application specific. Extensive performance data of YS 770 in various substrates and for various applications is available upon request.
