Tiangang® HS-200A

Oligomeric Hindered Amine light stabilizer (HALS)

Chemical name1,6-Hexanediamine, N,N'-bis(2,2,6,6-tetramethyl-4-piperidinyl)-, Polymers with 2,4,6-trichloro-1,3,5-triazin, reaction products with N-butyl-1-butanamine and N-butyl-2,2,6,6-tetramethyl-4-piperidinamine
CAS number192268-64-7
Tiangang® HS-200A is a highly effective radical scavenger that protects organic polymers against degradation caused by exposure to ultraviolet radiation. It is an oligomeric HALS characterized by extremely low volatility, high thermal stability and excellent compatibility with many substrates. Its oligomeric structure makes it particularly effective when used in thin section articles such as fiber and film. Tiangang® HS-200A is suited for use in polypropylene, LDPE, HDPE, XPE, EVA and PP blends with elastomers. Tiangang® HS-200A is also effective as an antioxidant for long term thermal stability. Tiangang® HS-200A can directly replace Chimassorb 2020.
