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.

1. UV-944/Light Stabilizer-944 used as a light stabilizer in polypropylene (PP), polyethylene (PE), and other polyolefins.
2.UV-944/Light Stabilizer-944 Provides UV protection for automotive parts, agricultural films, and outdoor furniture.
3. UV-944/Light Stabilizer-944 enhances weatherability in engineering plastics such as ABS, HIPS, and polycarbonate blends.
4.Suitable for fiber and tape applications due to its low extractability and high thermal stability.
5. UV-944/Light Stabilizer-944 used in coatings and adhesives to improve resistance to sunlight and oxidative degradation.
UV-944 is considered safe for use in industrial applications when handled properly. It is non-toxic and non-irritating under normal conditions of use. However, appropriate personal protective equipment (PPE) such as gloves and dust masks is recommended during handling to avoid inhalation or contact with eyes and skin.
Store in a cool, dry, and well-ventilated area.
Keep away from heat, sparks, and open flames.
Keep container tightly closed when not in use.
Avoid contact with strong oxidizing agents.
UV-944 is typically supplied in 20 kg woven bags with inner polyethylene liner or 25 kg fiber drums.
Also available in 500 kg or 1000 kg palletized bags upon request.
Classified as non-hazardous for transport.
