1843-05-6 – Справочная информация
| benzophenone ultraviolet absorber | ultraviolet absorber UV-531 belongs to benzophenone ultraviolet absorber, chemical name 2-hydroxy-4-n-octanoxy benzophenone, light yellow needle-like crystalline powder at room temperature, is a high-efficiency anti-aging additive with excellent performance, can strongly absorb 270 ~ 340nm ultraviolet light, it has the characteristics of light color, non-toxic, good compatibility, low mobility and easy processing. It is widely used in PE, PVC, PP, PS, PC, plexiglass, polypropylene fiber and ethylene vinyl acetate. And for dry phenolic and alkyd varnishes, polyurethane, acrylic, epoxy and other air drying products and automotive finishing paint, powder coatings, polyurethane, rubber products, etc., it provides them with good light stabilization effect. Dosage 0.1%-0.5%. Ultraviolet absorber UV-531 has excellent protective effect on polymers, and helps to reduce color, while delaying yellowing of materials and preventing loss of physical properties. UV-531 has good compatibility with polyolefin, has low volatility, can effectively prevent losses in the processing process, and has no effect on the odor of the product itself, has excellent compatibility with thermoplastic resin, and can be evenly distributed in the polymer during processing. Ultraviolet absorbers are UV-531 in powder and flake forms. The flaky 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. |

| uses and characteristics | ultraviolet absorber UV-531 is a high-efficiency anti-aging aid with excellent performance. it can absorb 240-340 nm ultraviolet light and has the characteristics of light color, non-toxicity, good compatibility, low mobility and easy processing. It has the greatest protective effect on polymers, and helps to reduce color, while delaying yellowing and blocking the loss of physical properties. It is widely used in PE, PVC, PP, PS, PC, plexiglass, polypropylene fiber and ethylene vinyl acetate. And for dry phenolic and alkyd varnishes, polyurethane, acrylic, epoxy and other air drying products and automotive finishing paint, powder coatings, polyurethane, rubber products, etc., it provides them with good light stabilization effect. Dosage 0.1%-0.5%. |
| ultraviolet absorber | UV-531 ultraviolet absorber used in polymers and vinyl products, it can strongly absorb ultraviolet rays of 300 ~ 375nm. High and low density polyethylene: pipes, plastic greenhouses (combined with LOWILITEQ84 can obtain enhanced effect, with high efficiency and pesticide resistance). Polypropylene (fiber grade, etc.) polyolefin copolymer (EPR, EPDM, EVA…) PVC, polyester, artificial resin, PS, ABS. UV-531 is standard for food packaging materials in many countries. The general dosage is 0.2 ~ 0.6%. In order to prevent caking, the UV-531 should be transported and stored at 30~35 ℃. |
| магазин | avoid yang, high light, moisture, and avoid light stabilizers containing sulfur or halogen elements. It needs to be stored under sealed, dry and dark conditions. |
| приложению | mainly used as light stabilizer for polyethylene, polypropylene, polyvinyl chloride, polyurethane rubber and other synthetic materials widely used in PE, PVC, PP, PS, PC, polycarbonate, plexiglass, polypropylene fiber and ethylene acetic acid and other aspects. And for dry phenolic and alkyd varnishes, polyurethane, acrylic, epoxy and other air drying products and automotive finishing paint, powder coatings, rubber and other products, it provides them with good light stabilization effect. Dosage 0.1-0.5%. |
| способ производства | the mixture of 2, 4-dihydroxybenzophenone, 1-bromon-octane, acetone and potassium carbonate is heated and reacted, filtered, concentrated, cooled, filtered, concentrated, cooled and filtered, and the obtained crude product is recrystallized with ethanol. Got to UV-531. Raw material consumption quota: 2,4-dihydroxybenzophenone 935kg/t, 1-bromon-octane 1265kg/t, potassium carbonate (95.5%)910kg/t, acetone 1040kg/t. |
