Octabenzone

Product Overview

Octabenzone, widely recognized in the industry as UV-531 or BP-12, stands as a premier benzophenone-type ultraviolet absorber. This high-performance chemical additive is engineered to protect organic materials from the detrimental effects of UV radiation. By effectively absorbing harmful wavelengths between 240 and 340 nanometers, it safeguards polymers and coatings from photodegradation, ensuring extended product lifecycles and maintained aesthetic quality. Our manufacturing process adheres to strict international quality standards, delivering a product with exceptional purity and consistent performance across diverse industrial applications.

As a critical component in material science, Octabenzone functions by dissipating absorbed UV energy as harmless thermal energy. This mechanism prevents the breaking of chemical bonds within the polymer matrix, thereby reducing yellowing, cracking, and loss of mechanical strength. The compound is characterized by its low volatility, excellent compatibility with various resin systems, and minimal migration properties, making it an ideal choice for long-term stabilization requirements.

Technical Specifications

Industrial Applications

The versatility of Octabenzone allows it to be integrated into a wide array of material formulations. It is extensively utilized in the plastics industry, providing robust protection for polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), and polycarbonate (PC). In these applications, it prevents the embrittlement and discoloration often caused by prolonged sunlight exposure. Furthermore, it is highly effective in polypropylene fibers and ethylene vinyl acetate copolymers, ensuring durability in outdoor textiles and packaging materials.

Beyond plastics, this UV absorber plays a vital role in the coatings and paints sector. It enhances the light stability of alkyd varnishes, polyurethanes, acrylics, and epoxy systems. Automotive finishing paints and powder coatings benefit significantly from its inclusion, as it helps maintain gloss and color fidelity over time. Rubber products also utilize Octabenzone to prevent surface cracking and degradation. The recommended dosage typically ranges from 0.1% to 0.5%, depending on the specific substrate and desired level of protection.

Key Advantages

• Superior UV absorption capacity in the critical 240-340nm range.
• Excellent compatibility with most common polymer resins and coating systems.
• Low volatility ensures stability during high-temperature processing.
• Non-toxic and safe for use in various consumer and industrial products.
• Effectively retards yellowing and physical property loss.
• Low migration properties prevent blooming on product surfaces.

Storage And Handling

Octabenzone is classified as a stable chemical substance under normal conditions. It is non-flammable, non-explosive, and non-corrosive, facilitating safe transportation and storage. The product should be kept in a cool, dry, and well-ventilated area, away from direct sunlight and moisture. Standard packaging involves cardboard drums lined with plastic bags, with a net weight of 25kg per drum. Custom packaging solutions are available to meet specific logistical requirements. With proper storage, the material maintains its integrity and performance characteristics for extended periods, ensuring reliability for your production schedules.
