Tinuvin 622 is the light stabilizer of choice for all applications calling for low volatility and minimal migration, because of its oligomeric structure with hogh molecular weight.
Furthermore Tinuvin 622 is effective as antioxidant and contributes significantly to the long term heat stability of polyolefines and tackifier resins.
Tinuvin 622 areas of application include polyolefines (PP, PE), olefine copolymers such as EVA as well as blends of polypropylene with elastomers.
In addition Tinuvin 622 is highly effective in polyacetals, polyamides, and polyurethane applications. |
