For R&D scientists and product formulators, a deep understanding of chemical intermediates' properties is crucial for successful innovation. Hydrogenated Bisphenol A (HBPA), identified by CAS No. 80-04-6, is a high-performance cycloaliphatic diol offering a unique set of advantages. NINGBO INNO PHARMCHEM CO.,LTD., as a dedicated manufacturer and supplier of HBPA, provides essential technical insights to help you leverage its full potential.

The fundamental difference between HBPA and its aromatic precursor, Bisphenol A (BPA), lies in the saturation of the phenolic rings, achieved through a catalytic hydrogenation process. This structural modification imbues HBPA with significantly enhanced UV stability and thermal resistance. These properties are critical for materials designed to perform under demanding conditions, where exposure to sunlight or elevated temperatures can cause degradation in less robust compounds. When you intend to buy HBPA, understanding these core technical advantages is key to optimizing your formulations.

Key Technical Properties of HBPA

HBPA typically presents as a white crystalline flake or powder, with a high purity level, often exceeding 99% as determined by Gas Chromatography (GC). Its melting point generally falls within the range of 156-160°C, indicating a stable solid at room temperature. The hydroxyl value, typically around 470-490 mg KOH/g, signifies its reactivity as a diol in polymerization processes. Unlike BPA, HBPA exhibits excellent solubility in organic solvents like ethanol but is insoluble in water, a characteristic that can influence its use in specific solvent-based systems.

The most significant technical benefits of HBPA stem from its improved weatherability and resistance to thermal decomposition (decomposing above 300°C). This makes it an ideal candidate for applications requiring long-term performance without significant degradation or yellowing. Its chemical inertness further adds to the durability of materials derived from it.

Applications Driven by Technical Superiority

These superior properties translate into diverse applications. In the coatings industry, HBPA enhances UV resistance and reduces yellowing in resins for exterior applications. For electronics, it is vital for clear, stable LED encapsulants and insulating materials. Furthermore, HBPA is used as a building block for high-performance polycarbonates and specialty resins that demand excellent thermal stability and optical clarity. For formulators looking to achieve superior material performance, integrating HBPA is a strategic choice.
