  • UV stabilizer UV 531 performance


    Other name of UV stabilizer
    UV absorber,UV additive
    Chemical Name: 2-Hydroxy-4-Octyloxy Benzophenone (Benzophenone-12)
    CAS NO: 1843-05-6


    Property of UV 531
    UV stabilizer additives freely soluble in benzene, n-hexane, acetone, slightly soluble in ethanol, very slightly
    soluble in ethane dichloride.


    Characteristic
    UV stabilizer 531 is a light stabilizer with good performance, capable of absorbing the UV radiation of 240-340 nm
    wavelength with the characteristics of light color, nontoxic , good compatibility,small mobility, easy processing etc.
    uv stabilizers in plastics can protect the polymer to its maximum extent, helps to reduce the color.uv stabilizers in
    plastics can also delay the yellowing and obstacle the loss of its physical function.
