  3. The main application of UV Absorber 531 is in combination with a HALS the
    light stabilization of low density and linear low density polyethylene as well
    as ethylene-vinyl acetate copolymers for agricultural films. It can be used as
    well as a UV barrier to protect the contents of packages for both industrial
    and consumer applications. Also, in combination with HALS, UV Absorber 531
    can be used in high density polyethylene molded articles, e. g. in crates.
    UV Absorber 531 also protects a number of other polymers against degradation
    caused by light exposure such as plasticized PVC and rubbers.
    UV Absorber 531 can be used in combination with antioxidants, phosphites
    and other light stabilizers.
  4. Octabenzone is mainly used as light stabilizer for synthetic materials such as polyethylene, polypropylene, polyvinyl chloride and polyurethane rubber
  5. Octabenzone is widely used in PE, PVC, PP, PS, PC, polycarbonate, plexiglass, polypropylene fiber and vinyl acetate. Moreover, it provides good light stability for dry phenolic and alkyd varnish, polyurethane chemical book, acrylic acid, epoxy and other air drying products, as well as automotive finishing paint, powder coating, rubber and other products. Dosage: 0.1-0.5%.
  6. Octabenzone is a high-efficiency anti-aging additive with excellent performance. It can absorb 240-340nm ultraviolet light. It has the characteristics of light color, non-toxic, good compatibility, small mobility and easy processing. It has the greatest protective effect on polymers, helps to reduce color, delay yellowing and block the loss of physical properties. It is widely used in PE, pcchemicalbook VC, PP, PS, PC Plexiglass, polypropylene fiber, ethylene vinyl acetate, etc. it also provides good light stability for dry phenolic and alkyd varnish, polyurethane, acrylic, epoxy and other air drying products, automotive finishing paint, powder coating, polyurethane, rubber products, etc. the dosage is 0.1% – 0.5%
  7. Octabenzone belongs to benzophenone ultraviolet absorber, with chemical name of 2-hydroxy-4-n-octoxybenzophenone. It is light yellow acicular crystalline powder at room temperature. It is a high-efficiency anti-aging additive with excellent performance. It can strongly absorb 270 ~ 340nm ultraviolet light. It has the characteristics of light color, non toxicity, good compatibility, small mobility and easy processing. It is widely used in PE PVC, PP, PS, PC, plexiglass, polypropylene fiber and vinyl acetate. Moreover, it provides good light stability for dry phenolic and alkyd varnish, polyurethane, acrylic, epoxy and other air drying products, as well as automotive finishing paint, powder coating, polyurethane and rubber products. Dosage: 0.1% – 0.5%.
  8. Octabenzone has excellent protective effect on the polymer and helps to reduce the color, delay the yellowing of the material and block the loss of its physical properties. UV-531 has good compatibility with polyolefin, low volatility, can effectively prevent loss in the processing process, has no impact on the smell of the product, has excellent compatibility with thermoplastic resin, and can be evenly distributed in the polymer during processing. UV absorber UV-531 has two forms: powder and sheet. Flake uv531 is easy to add in use, can reduce dust flying, is relatively environmentally friendly, and reduces the processing difficulty, so it is widely used.
  9. Octabenzone is an ultraviolet absorber for polymers and vinyl products, which can strongly absorb ultraviolet rays of 300 ~ 375 nm. High and low density polyethylene: pipe and plastic greenhouse (combined with lowiliteq84 to obtain enhanced effect and high agricultural drug resistance). Polypropylene (fiber grade, etc.) polyene chemicalbook hydrocarbon copolymer (EPR, EPDM, eva…) PVC, polyester, artificial resin, PS, ABS. UV-531 has been standardized in many countries for food packaging materials. The general dosage is 0.2 ~ 0.6%. In order to prevent caking, UV-531 should be transported and stored at 30 ~ 35 ℃.
