Tinuvin® XT 855 FF

Technical Datasheet | Supplied by BASF
Tinuvin® XT 855 FF by BASF is hindered amine derivative. It is a high performance, non-interacting light stabilizer system which imparts outstanding weatherability to polyolefin based compounds, even in presence of acidic species. It also contributes significantly to the long-term thermal stability of polyolefins based compounds. It is used for polyolefin based compounds and other plastics. Its use is especially recommended for the stabilization of blends of polypropylene with elastomers (TPO), especially for paintable automotive applications. Other applications include molded-in-color TPO, TPE, TPV, and polypropylene. The use levels of Tinuvin® XT 855 FF range between 0.05 and 0.8%, depending on the substrate and the performance requirements of the final application.
