Hindered Amine Light Stabilizer Ultraviolet Absorbent, Uv Stabilizer 622 Hals 622

Basic Spec

Chemical name Polysuccinic acid (4-hydroxy-2,2,6,6-tetramethyl-1-piperidineethanol) ester
Poly-(N-β-hydroxyethyl-2,2,6,6-tetramethyl-4-hydroxy-piperidyl succinate)

Molecular formula:C21H26O3
Molecular weight:326.1

CAS NO : 65447-77-0

Light stabilizer 622 is a polymeric high molecular weight hindered amine light stabilizer, which is an oligomer, has good processing heat stability and good compatibility with various resins, and is also a high molecular weight compound. The light stabilizer 622 has excellent water extraction resistance, and therefore, water resistance is good and is not easily lost during processing or during use. This product can effectively prevent the degradation of high polymer by light, heat, climate and moisture. It is much superior to general low molecular weight hindered amine light stabilizers (HALS). The polymeric hindered amine has better heat resistance, resistance to extraction, lower volatility and mobility. As a light stabilizer, the product is suitable for polyethylene, polypropylene, polystyrene, olefin copolymer, polyester, soft polyvinyl chloride, polyurethane, polyoxymethylene and polyamide.

Physical Specification:

Light stabilizer 622 has excellent processing thermal stability, low volatility and resistance to migration, extraction, and gas fading.
It has good compatibility with resin, good water extraction resistance, and excellent long-term anti-light compared with general low molecular weight hindered amine light stabilizer.
Aging nature.


Light stabilizer 622 is mainly used for PE longevity film, and can also be used for polyurethane, polyacetal, especially for nylon 11 and nylon 12 and
Ester elastomer. This product has synergistic effect with UV absorber, and has excellent anti-oxidation effect. It has good compatibility with resin and is widely used in polyene.
On hydrocarbon food packaging materials.


Net 25KGS/two-layer PE bag in carton/drum, or as required


Because of the low performance on hydrolyzing resistance, protectionfrom moisture and heat is needed.
