Hindered Amine Light Stabilizer (High MW)
High-molecular-weight oligomeric hindered amine light stabilizer (HALS) based on a polymeric piperidine structure, providing outstanding durability in polyolefin films, fibers, and thick-section plastics. The high molecular weight minimizes volatility and extractability, ensuring the stabilizer remains effective throughout the lifetime of the product. Particularly effective in polypropylene and polyethylene applications.
