Function:
Light stabilizer UV-944, also known as light stabilizer HS-944, is white to light yellow granules or powders, with a melting point of 100-135°C and a molecular weight of 2000-3100. Chemicalbook has excellent compatibility, extraction resistance and low volatility. Since UV-944 is a high relative molecular weight stabilizer and contains only a large amount of methine in the molecule, it is stable during thermal oxidation treatment.
Light stabilizer UV-944 has good extraction resistance and is particularly suitable for thin products such as fibers and films; it can also improve the material’s resistance to thermal oxidation aging.
Application:
Hindered amine light stabilizer 944 is suitable for low-density polyethylene film, polypropylene fiber, polypropylene tape, EVA film, ABS, polystyrene and food packaging.
