Chemical Properties

Description
Octabenzone(1843-05-6) appears as light yellow/yellowish crystals/fine powder and is odourless and freely soluble in benzene, n-hexane, and acetone; slightly soluble in ethanol; and very slightly soluble in ethane dichloride. Octabenzone is a light stabiliser with good performance, capable of absorbing the UV radiation of 240–340 nm wavelength with the characteristics of light colour, non-toxicity, good compatibility, small mobility, easy processing, etc. Octabenzone protects the polymer to its maximum extent and helps to reduce its colour. It can also delay the yellowing and impede the loss of its physical function. Industrial applications of octabenzone is very extensive and applied to PE, PVC, PP, PS, PC, organic glass, polypropylene fibre, ethylene-vinyl acetate, etc. Also, octabenzone has very good light-stability effect on drying phenol aldehyde, varnish of alcohol and acname, polyurethane, acrylate, expoxnamee, etc. The major uses include UV stabiliser, for example, polyethylene and polypropylene fibres.
