Hindered Amine light stabilizer (HALS)
Chemical name | Bis(2,2,6,6-tetramethyl-4-piperidyl)-sebaceate |
CAS number | 52829-07-9 |
Structure | |
Description | Tiangang® HS-770 is a highly effective radical scavenger that protects organic polymers against degradation caused by exposure to ultraviolet radiation. It is widely used in a variety of applications including polypropylene, polystyrene, polyurethanes, ABS, SAN, ASA, polyamides and polyacetals. Its high effectiveness as a light stabilizer makes it well suitable for applications in both thick section and films, independent of the thickness of the articles. Combined with Tiangang’s other HALS products, Tiangang® HS-770 displays strong synergistic effects. |
