UV Stabilizer 944 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. UV Stabilizer 944 is suited for use in polypropylene, LDPE, HDPE, XPE, EVA and PP blends with elastomers. UV Stabilizer 944 is also effective as an antioxidant for long term thermal stability.
