LS-622 is Oligomeric Hindered Amine Light Stabilizer. It is low volatility and minimal migration because of its oligomeric structure with high molecular weight. Furthermore, LS-622 is effective as antioxidant and contributes significantly to the long- term heat stability of polyolefins and tackifier resins. LS-622 areas of application include polyolefins (PP, PE), olefin copolymers such as EVA as well as blends of polypropylene with elastomers.
