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
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 polymers 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.
