Description

Bisphenol A CAS NO 80-05-7 is a high-purity industrial organic compound that serves as a critical monomer and intermediate in modern polymer manufacturing. Its primary value lies in its dual phenolic functionality, which enables the production of durable, high-performance plastics and resins. This essential chemical is in high demand across the plastics, epoxy resin, and polycarbonate industries for creating materials with excellent clarity, strength, and thermal stability.

Application

• Polycarbonate Plastic Production: The principal monomer for manufacturing clear, shatter-resistant polycarbonate used in eyewear lenses, electronic device housings, and safety glazing.
• Epoxy Resin Synthesis: A key precursor in producing epoxy resins, which are essential for high-performance coatings, adhesives, and composite materials.
• Flame Retardants: Used in the synthesis of certain halogenated compounds that act as effective flame retardants in plastics and textiles.
• Thermal Paper Manufacturing: Employed as a color developer in the coating of thermal receipt and fax paper.
• PVC Stabilizers: Serves as an intermediate in the production of certain polymer stabilizers.
• Other Polymer Modifiers: Used in the manufacture of polysulfones, polyetherimides, and other engineering plastics.
