Hindered Amine Light Stabilizer Ultraviolet Absorbent, Uv
Stabilizer 622 Hals 622
Chemical name Polysuccinic acid
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
Appearance white powder
Melting point 55-71 ° C
Volatile matter ≤0.1%
Light transmittance 425nm ≥95%, 500nm ≥97%
TGA (10%) 357 ° C
Light stabilizer 622 has excellent processing thermal stability,
low volatility and resistance to migration, extraction, and gas
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.
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.
It should comply with the chemical operation specifications, be
careful to avoid unnecessary contact. For more information, please
request a chemical from our sales representative.
