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.
