JADEWIN UV 531

Pale yellow crystal, the melting point is between 47 and 49 degrees Celsius, Soluble in benzene, n-hexane, acetone, slightly soluble in ethanol, slightly soluble in dichloroethane. It is a kind of high efficiency anti-aging agent with excellent performance, can absorber UV at 300-375nm, and it has many characteristics such as light color, non-toxic, good compatibility, small migration and easy processing etc. It has the greatest protective effect on the polymer, and helps to reduce the color, while delaying yellowing and retarding the loss of physical properties
