Ultraviolet Absorber TYSORB UV-360 Chemical name: 2,2'-methylenebis(4-t-octyl -6-(benzotriazolyl)- phenol) Trade name synonyms: Tinuvin 360 (Ciba Specialty Chemicals) CAS No.: 103597-45-1 Molecular Weight: 659 Specification: Appearance: off-white powder M.p: 194-8 Assay: ≥99%(HPLC) Transmittance: 440nm ≥ 97% 500nm ≥98% Solubility: Solubility(20 ) g/100g solvent acetone 0.05 ethanol 0.025 n-hexane 0.03 methylenen dichloride 75 ethyl acetate 0.06 chloroform 100 toluene 34 water < 0.01 * Application : UV-360 is particularly suitable for processing and aging conditions where high loads,low volatility and good compatibility are required.The specific objective is to achieve high UV-screen performance and minimize sublimation through vents as well as prevention of deposits on molds, chill-rolls or calibrators. It can prevent exudation/crystallization on end-parts during manufacturing or exposure to high service temperatures. Such requirements are especially critical for complex moldings,fibers,sheets,twin wall sheets,thin films,adhesive layers and laminated or coextruded semi-finished parts. Depending on equipment,processing conditions,and polymer types,UV-360 allows direct two-layer coextrusion of sheets without the use of a neutral third top layer to prevent sublimation and/or deposits generated by the thin,highly UVA-loaded second layer. The use level of UV-360 is 0.2-10% by weight,and it can be readily incorporated into the polymer by conventional technique such as powder,solution or melt blending. UV-360 can be used alone or in a variety of blends and combinations with antioxidants,other UV absorber and light stablizers,and some other functional stabilizers where often a synergistic performance is observed. * Packaging:Net weight:25kg/paperboard drum * Storage and shipment:It is stable during storage and shipment, avoiding high temperature and humidity.
