For professionals in material science and manufacturing, a deep understanding of chemical properties is key to successful product development. NINGBO INNO PHARMCHEM CO.,LTD. provides an in-depth look at the technical specifications of Optical Brightener FP-127, highlighting the scientific basis for its exceptional performance as a fluorescent whitening agent.

Optical Brightener FP-127, identified by its CAS number 40470-68-6, possesses a unique molecular structure that enables its remarkable optical properties. Its chemical name, 4,4′-bis(2-methoxystyryl)-1,1′-biphenyl, points to a conjugated system capable of absorbing UV light (typically around 359-368nm) and emitting visible blue light (around 436nm). This precise fluorescence mechanism is what delivers the enhanced whiteness and brightness to materials.

The technical data for this fluorescent whitening agent FP-127 often includes details such as a high purity level (typically ≥99%), a specific melting point range (219-221°C), and a fine particle size (e.g., ≥300 meshes). These attributes are crucial for uniform dispersion within polymer matrices, coatings, and inks, ensuring consistent whitening effects. Manufacturers looking to buy optical brightener FP-127 should pay close attention to these specifications to match their processing requirements.

Furthermore, the excellent thermal stability of FP-127 fluorescent brightener, with decomposition temperatures often exceeding 300°C, allows it to endure the high temperatures encountered during plastic processing without degradation. Its good compatibility with various polymer systems, including PVC and polystyrene, and its resistance to weathering and light are direct results of its stable chemical structure. These properties make it a superior choice compared to less stable alternatives.

The consistent quality and predictable performance of Optical Brightener FP-127 are why it is sought after by optical brightener FP-127 manufacturers and end-users alike. Understanding these technical nuances allows formulators to optimize dosage and processing parameters, ensuring they leverage the full potential of this plastic whitening agent FP-127. NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing technically sound products that meet the rigorous demands of modern manufacturing.
