  • Description Octabenzone is a UV absorber/screener. It is used to protect polymers (e.g., polyethylene, polypropylene, polyvinylchloride) against damage by UV light. Colorless crystals; Light yellow powder. Stable under recommended storage conditions. Octabenzone 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.
  • Uses Adsorbents and absorbents; Paint additives and coating additives not described by other categories Processing aids, not otherwise listed Air Care Products Building/Construction Materials not covered elsewhere Fabric, Textile, and Leather Products not covered elsewhere Furniture and Furnishings not covered elsewhere Paints and Coatings Plastic and Rubber Products not covered elsewhere To stabilize polyethylene against deterioration by ultraviolet light. HOBPs are UV absorbers for insulating plastics, which can be incorporated with active layers to increase the stabilization of organic solar cells (OSCs). It may be incorporated in parylene C films to enhance the light stability, which can be potentially used as a moisture transfer membrane for electronic boards and photovoltaics.
