Product Details
Chemical name: 2-Hydroxy-4-n-octoxybenzophenone CAS No.?1843-05-6 Molecular formular?C21H26O3 Molecular weight?326 Molecular structure Specification Appearance: Pale yellow crystalline powder Melting point???47-49 Purity (HPLC), %: ? 99 Ash, %: ?0.1 Loss on Drying, %: ?0.5 Transmittance 450nm?90% 500nm?95% Solubility (20?, g/100ml solvent) Acetone:43 Chloroform:61 Ethanol:4 Ethyl Acetate:44 n-Hexane:12 Methanol:2 Methylene chloride:67 Toluene?50 Water?0.01 Application UV ABSORBER HOSORB-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. 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, varnis of alcohol and acname, polyurethane, acrylate, expoxnamee etc. Packing 25kg/fiber drum; 25kg/carton, or as per customer’s request. Storage Containers should be kept tightly closed when not in use. Store it in a dry, cool, well-ventilated shady place. Recommended Dosage 0.1-0.5%
