TINUVIN 791 FB
TINUVIN 791 FB
Tinuvin 791 is a synergistic mixture of Chimassorb® 944 and Tinuvin 770. It is an excellent light stabilizer especially for PP thick sections, which offers excellent surface protection. It also shows high stabilization efficiency in PP tapes.
Applications
Tinuvin 791 areas of application are PP, blends of polypropylene with elastomers and PA: It can also be used in styrenic polymers, e. g. ABS, impact polystyrene, etc.
Features & Benefits
Tinuvin 791 is an excellent UV stabilizer for thick sections, e. g. automotive bumpers, fascia, garden furniture etc.
The synergism between the high and low molecular weight HALS components of Tinuvin 791 guarantees maximum protection for the polymer against degradation from UV radiation and long-term heat exposure.
