Siwin-LS622
Light stabilizer
Light stabilizer 622 is a polymeric high molecular weight hindered amine light stabilizer, with low volatility, migration resistance, low alkalinity and high temperature resistance. It has synergetic effect with antioxidants and UV absorbers.
Typical Physical Properties
Chemical Name:Poly(4-hydroxy-2,2,6,6-tetramethyl-1-piperidine ethanol-alt-1,4-butanedioic acid)
Cas No.:65447-77-0
Appearance | White crystal powder or granules |
Light transmittance | ≥98% （425nm） ≥99% （500nm） |
Molecular weight | >3000 g/mol |
Melting point | ≥50℃ |
Volatiles | ≤0.5% |
Ash | ≤0.1% |
Applications
It is effective in a broad range of polymers and applications. The product is particularly usefully in PE applications (injection molding, rotational molding, film, and tape), EVA, PP fibers, polyurethanes, polyacetals, polyamide, elastomers, adhesives etc. It is usually used in combination with antioxidants, UV absorbers to optimize performance in outdoor use.
Packaging and Storage
Package: 25kg carton inner with plastic bag or as customer`s requirement.
Storage: Keep container tightly closed in a dry and well-ventilated place.
The use of proper protective equipment is recommended. Excess exposure to the product should be avoided. Wash thoroughly after handling.
All safety information is provided in the Safety Data Sheet.
