Description
Bisphenol A (BPA, CAS 80-05-7) is a synthetic organic compound produced by the condensation of acetone with two equivalents of phenol. Also referred to as dian or bisphenol, it serves as a primary monomer and building block in the synthesis of polycarbonate resins and epoxy systems.
In epoxy coatings and adhesives, BPA reacts with epichlorohydrin to form diglycidyl ether resins that cure into hard, chemically resistant networks. In polycarbonate production, it undergoes polycondensation to yield transparent, high-impact thermoplastics used across electronics and automotive components. It also functions as an antioxidant and UV stabilizer in polymer formulations.
Bisphenol A is supplied as white to tan crystalline flakes or in liquid form, with industrial and technical grades available. It falls under REACH regulation and is classified as a substance of very high concern (SVHC), requiring compliance documentation. Standard packaging includes 25 kg bags and bulk quantities. HS code: 29072300.
