What is UV-944 /Light Stabilizer-944？

UV-944/Light Stabilizer-944 is a high-performance polymeric hindered amine light stabilizer (HALS) widely used in plastics and polymer industries to protect materials from degradation caused by UV radiation. It effectively prevents discoloration, loss of mechanical properties, and surface cracking. UV-944 is known for its excellent compatibility with polyolefins, ABS, and other engineering plastics. It is also recognized under the trade name Chimassorb 944. Its high molecular weight ensures low volatility and minimal migration, making it ideal for long-term outdoor applications.
