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