Description
intro:
Low Molecular Weight Hindered Amine Light
Stabilizer　(HALS)
Characterization YS **0 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,*-tetramethyl**-piperidyl) sebaceate
CAS Number *********9
Structure YS **0
Molecular Weight:**0.*4
Applications YS **0 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 **0 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 **0 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 **0
is less dependent on the polymer’s thickness. For this reason the
use of YS **0 also provides good light stability in articles with
higher specific surface, e.g.films and tapes.
Combined with other HALS YS**0 is part of other synergistic blends,
e.g. YS **1
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 **0 in various substrates and for various applications
is available upon request.
