Light Yellow / White Crystalline Powder Tinuvin 622 HALS Light
Stabilizer , CAS No. 41556 - 26 – 7
Quick Detail :
LS 622 is the light stabilizer of choice for all applications
calling for low validity and minimal migration , because of its
oligomeric structure with high molecular weight . Furthermore , LS
622 is effective as antioxidant and contributes significantly to
long term heat stability of polyolefins and tackifier resin .
- Name : LS 622
- Chemical name :
Poly ( 4 - hydroxy - 2 , 2 , 6 , 6 - tetramethyl - 1 - piperidine
ethanol - alt - 1 , 4 - butanedioic acid )
- CAS No. : 41556 - 26 - 7
- Function : Low volatility , Exceptional light absorbing
characteristics and can get a better performance in the use of
combination with other UV absorbers as well as antioxidants .
LS 622 areas of application include PP , PE , olefin copolymers
such as EVA as well as blends of polypropylene with elastomers . In
addition , LS 622 is highly effective in polyacetals , polyamides
and polyurethane applications .
