Chimassorb 944

Chimassorb 944 is a polymeric hindered amine light stabilizer (HALS) based on a triazine-piperidine backbone, offering excellent resistance to extraction, migration, and volatilization due to its high molecular weight. It delivers outstanding long-term thermal and UV protection in polyethylene, polypropylene, and various polyolefin-based films, fibers, tapes, and molded parts. Key benefits include low volatility during processing, strong compatibility with common polymer systems, and effective performance even at low loadings. Typical downstream users include manufacturers of agricultural films, geomembranes, greenhouse covers, raffia, automotive components, and outdoor plastic goods requiring durable weathering performance.
