Key Properties
Bisphenol A (BPA) is an aromatic organic compound with the molecular formula C₁₅H₁₆O₂ and CAS No. 80-05-7. It appears as a white crystalline solid or flakes and is slightly soluble in water but soluble in many organic solvents. BPA contains two phenolic hydroxyl groups, making it highly useful in polymer and resin synthesis.
Key Features
BPA is a key raw material for epoxy resins and polycarbonate plastics. It provides excellent mechanical strength, thermal resistance, transparency, and chemical resistance in downstream products. In epoxy systems, BPA helps improve adhesion, durability, corrosion resistance, and electrical insulation performance.
Main Applications
Bisphenol A is widely used in the production of epoxy resins, polycarbonate plastics, flame retardants, coatings, adhesives, electronic materials, and composite materials. It is especially important in epoxy resin systems for industrial coatings, electrical insulation, marine coatings, wind energy composites, and construction materials.
Production Process
Bisphenol A is mainly produced by the condensation reaction of phenol and acetone under acidic catalytic conditions. The crude product is then purified through crystallization and filtration to obtain high-purity BPA for resin and polymer production.
