For industries that rely on visual appeal, the science of brightness is as important as the function of the product itself. Optical Brightener FP-127 stands out as a highly effective fluorescent whitening agent, prized for its ability to enhance whiteness and vibrancy across a spectrum of materials. NINGBO INNO PHARMCHEM CO.,LTD. is a leading supplier of this crucial additive, and understanding its core chemical properties is key to appreciating its broad applicability.

At its core, Optical Brightener FP-127 is a complex organic compound with the chemical name 4,4′-Bis(2-methoxystyryl)-1,1′-biphenyl. Its molecular formula is C30H26O2, and it possesses a molecular weight of approximately 418.53 g/mol. The CAS number for this substance is 40470-68-6, which serves as its unique identifier in chemical databases and regulatory contexts. These fundamental chemical identifiers are crucial for formulators and researchers when specifying materials for their applications.

The physical specifications of FP-127 further elaborate on its nature and usability. It typically appears as a light yellowish powder. While this might seem counterintuitive for a whitening agent, its true magic lies in its fluorescent properties. Upon exposure to ultraviolet light, it emits a blue-violet fluorescence. This fluorescence compensates for the yellow tones often present in polymers, coatings, and inks, making the material appear significantly whiter and brighter to the human eye. The purity of FP-127 is generally stated as being 99% or higher, ensuring consistent performance and predictable results in formulations.

Key performance characteristics of this FP-127 fluorescent whitening agent include its impressive thermal stability, often cited as being greater than 300°C. This robust thermal resistance makes it ideal for incorporation into processes that involve high temperatures, such as plastic extrusion and molding, without degradation of its whitening capability. Additionally, its excellent light and weather resistance mean that the enhanced brightness it provides is long-lasting, resisting yellowing or fading over time. These properties are critical for applications where durability and sustained aesthetic appeal are required.
