UV absorber 531 Chemical Name: 2-Hydroxy-4-Octyloxy Benzophenone (Benzophenone-12) CAS NO: 1843-05-6 Molecular Formula: C21H26O3 Structural Formula: Property : ¢ÙYellowish crystals; ¢ÚYellowish fine powder Freely soluble in benzene, n-hexane, acetone, slightly soluble in ethanol, very slightly soluble in ethane dichloride. Specification Content£º¡Ý99 % Melting Point: 47~49 ¡ãC Ash: ¡Ü0.1 % Light Transmittance: (450nm)¡Ý90% (500nm)¡Ý95% Characteristics and Uses: This product 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. It can protect the polymer to its maximum extent, helps to reduce the color. It can also delay the yellowing and obstacle the loss of its physical function. It is widely applied to PE,PVC,PP,PS,PC organic glass, polypropylene fiber, ethylene-vinyl acetate etc. Moreover, it has very good light-stability effect on drying phenol aldehyde, varnish of alcohol and acname, polyurethane, acrylate, expoxnamee etc. Its dosage is 0.1%-0.5%. Package: packed in cardboard drums lined with plastic bags with the net capacity of 20 kg per bag. Precaution: No toxicity kept away from moisture and fire in transportation; stored and transported as common chemicals with relatively good stability. 25KG Carton or drum.
