Polymeric Hindered Amine Light Stabilizers (HALS) are indispensable additives for enhancing the durability and weatherability of plastics. At NINGBO INNO PHARMCHEM CO.,LTD., we are proud to be a leading manufacturer and supplier of high-performance polymeric HALS, offering solutions that protect a broad spectrum of polymer types. Our product, identified by CAS No. 71878-19-8, is formulated for optimal performance across various demanding applications.

The effectiveness of our polymeric HALS lies in their ability to scavenge free radicals generated by UV exposure, thereby preventing polymer degradation. Their inherent low volatility and excellent resistance to migration make them ideal for applications where long-term protection is paramount. Here are some key application areas where our stabilizers provide significant benefits:

• Polyolefins (PP, PE): This is a major application area. Our polymeric HALS are widely used in polypropylene (PP) and polyethylene (PE) products, including films, fibers, tapes, and molded articles. They are crucial for extending the outdoor service life of agricultural films, outdoor furniture, automotive components, and packaging materials made from these polymers.
• Olefin Copolymers (EVA): For ethylene-vinyl acetate (EVA) copolymers, especially those blended with elastomers, our HALS contribute to maintaining flexibility and preventing UV-induced cracking and degradation.
• Engineering Plastics: The high performance of our polymeric HALS makes them suitable for use in polyacetals (POM), polyamides (PA), and polyurethanes (PU). These materials often find applications in more demanding environments where UV resistance is critical.
• PVC and Related Materials: Both flexible and rigid PVC formulations benefit from the inclusion of our HALS, protecting against yellowing and embrittlement. They are also effective in certain styrenic elastomer applications and specialty adhesives requiring UV stability.
• Coatings and Adhesives: Beyond bulk polymers, our HALS can be incorporated into specialized coatings and adhesive formulations to enhance their resistance to weathering and maintain their aesthetic and functional properties over time.
