Bisphenol A (BPA) is a chemical compound used as a building block (monomer) primarily in the production of polycarbonate plastics and epoxy resins. Polycarbonate is a strong, transparent, and durable thermoplastic polymer used in various products, including some food containers, water bottles, baby bottles (now restricted in many places), CDs, DVDs, and eyeglasses. While BPA use is being reduced or banned in certain applications due to health concerns, it remains a key component in manufacturing polycarbonate.

– Bisphenol A (BPA) is an industrial chemical.
– It is a key structural component in the manufacture of polycarbonate plastic and epoxy resins.
– Polycarbonate is used in various consumer products.

Concerns about BPA stem from its potential to leach into food and beverages from containers and its classification as an endocrine disruptor, meaning it can interfere with hormonal systems. Many products are now marketed as “BPA-free,” indicating the use of alternative materials or manufacturing processes. LDPE, PET, and PVC are different types of plastics manufactured using different monomers and processes, and do not typically contain BPA.
