| Questions And Answer | Back Directory | [Characterization]
Light Stabilizer 622 is the light stabilizer of choice for all applications calling for low volatility and minimal migration, because of its oligomeric structure with high molecular weight. Furthermore Light Stabilizer 622 is effective as antioxidant and contributes significantly to the long-term heat stability of polyolefins and tackifier resins.
| [Applications]
Light Stabilizer 622 areas of application include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers. In addition Light Stabilizer 622 is highly effective in polyacetals, polyamides and polyurethane applications.
| [Features/benefits]
The effectiveness of Light Stabilizer 622 surpasses significantly that of UV absorbers, particularly in pigmented systems. Combinations of Light Stabilizer 622 with UV absorbers, e. g. Tinuvin range or other HALS, e. g. Chimassorb® range in many cases result in synergistic effects. Typical examples are Tinuvin 783 and Tinuvin 111.

| Hazard Information | Back Directory | [Uses]
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements. | [Materials Uses]
Light Stabilizer 622, as one of the hindered amine light stabilizers, has
excellent anti-light properties, and is widely used in plastic products
such as polyethylene, polystyrene and polypropylene. Its purpose is to
effectively protect plastic products from light- and heat-induced
degradation and thus prolong their service life.[1] | [References]
