High Molecular Weight Hindered Amine Light
Stabilizer (HALS)
Chemical Name: Butanedioic acid,
dimethylester, polymer with *-hydroxy
*2,2,6,*-tetramethyl**-piperidine ethanol.
Introduction: LS **2 is the light stabilizer of
choice for all applications calling for low volatility and minimal
migration, because of its oligomeric structure with high molecular
weight. Furthermore LS **2 is effective as antioxidant and
contributes significantly to the long term heat stability of
polyolefins and tackifier resins.
Details:
CAS Number *********0
Molecular Weight Mn = ***0 – ***0
Properties:
Appearance and behaviour White to slightly yellow powder,
odorless
Flash point >**0
℃
Applications:LS **2 areas of
application include polyolefins (PP, PE), olefin copolymers such as
EVA as well as blends of polypropylene with elastomers.
In addition LS **2 is highly effective in polyacetals, polyamides
and polyurethane applications.
Features / Benefits The effectiveness of LS **2 surpasses
significantly that of UV absorbers, particularly in pigmented
systems. Combinations of LS **2 with UV absorbers.
Packing：LS***2 is available in powder form in a *5kg
fiber drum or *5kg carton with an inner PE
liner.
