What is Light Stabilizer-944 CAS 70624-18-9？
UV-944, also known as light stabilizer HS-944, is white to light yellow particles or powder, melting point 100-135°C, molecular weight 2000-3100, with excellent compatibility, extraction resistance and low volatility. Since UV-944 is a high relative molecular mass stabilizer, and the molecule contains only a large amount of methylate, it is stable when treated with hot oxygen.
