UV-531: A Comprehensive Guide to an Effective UV Absorber and Light Stabilizer

UV-531, also known as BASF Chimassorb 81, BASF C81, Cytec Cyasorb 531, Cytec 531, UV Absorber UV-531, UV Absorber BP-12, Light Stabilizer UV-531, Light Stabilizer BP-12, 2-Hydroxy-4-n-octyloxybenzophenone, [2-Hydroxy-4-(octyloxy)phenyl]phenyl ketone, 2-Hydroxy-4-octyloxybenzophenone, Octabenzone, Benzophenone-12, BP-12, is a highly effective ultraviolet (UV) absorber and light stabilizer used in various industries, including plastics, coatings, adhesives, and fibers. INNO Specialty Chemicals, a leading manufacturer and supplier from China, produces high-quality UV-531 for global distribution.

UV-531 is a benzophenone-based UV absorber that provides excellent protection against UV radiation, which can cause degradation, discoloration, and other damages to materials. UV-531 absorbs UV radiation in the range of 270-340 nm and converts it into harmless heat, thus preventing photo-oxidation and other UV-induced reactions. UV-531 is particularly effective in protecting polymers, such as polyolefins, polycarbonates, polyesters, and polyamides, from UV degradation and extending their service life.

UV-531 is also a light stabilizer, which means it can protect materials from degradation caused by visible and infrared (IR) radiation. UV-531 absorbs IR radiation in the range of 700-1100 nm and converts it into heat, thus reducing thermal degradation and prolonging the stability of materials. UV-531 is especially useful in outdoor applications, such as automotive parts, construction materials, and agricultural films, where materials are exposed to both UV and IR radiation.

UV-531 has several advantages over other UV absorbers and light stabilizers. First, UV-531 has a broad absorption spectrum, which means it can protect materials against a wide range of UV wavelengths. Second, UV-531 has a high molar extinction coefficient, which means it can absorb more UV radiation per unit of concentration than other UV absorbers. Third, UV-531 has a low volatility and migration rate, which means it can remain in the material for a long time and provide long-lasting protection. Fourth, UV-531 has a low color contribution, which means it can maintain the original color and clarity of materials.

UV-531 can be used alone or in combination with other UV absorbers and light stabilizers to achieve optimal performance. For example, UV-531 can be combined with hindered amine light stabilizers (HALS) to provide synergistic protection against UV and thermal degradation. UV-531 can also be used with other benzophenone-based UV absorbers, such as UV-9 and UV-326, to broaden the absorption spectrum and enhance the photostability of materials.

In conclusion, UV-531 is a highly effective UV absorber and light stabilizer that provides excellent protection against UV and IR radiation. INNO Specialty Chemicals produces high-quality UV-531 for various applications and markets, including plastics, coatings, adhesives, and fibers. UV-531 has several advantages over other UV absorbers and light stabilizers, including a broad absorption spectrum, a high molar extinction coefficient, a low volatility and migration rate, and a low color contribution. UV-531 can be used alone or in combination with other UV absorbers and light stabilizers to achieve optimal performance.
