Bisphenpl A, also known as BPA is a chemical compound commonly used in making polycarbonate plastics and epoxy resins. Polycarbonate plastics are lightweight, durable, flexible, and have a high heat resistance. Many consumer products are made with polycarbonate plastics. Epoxy resin is a thermosetting polymer used for general adhesions and protective coatings (1). BPA can leech from packaging products like water bottles especially as they age and break down. Subsequently, BPA is ingested by people and recent studies have shown this chemical to be a hormone disruptor and may lead to breast and/or prostate cancer.
Polycarbonate plastics and epoxy resins containing BPA can be found in products such as drinking containers, plastic storage containers and cutlery, food and drink cans, bottle tops, dental sealants, water pipes and eye glass lenses. Polycarbonate can be blended with other plastics to create parts for vehicles, electronic equipment, medical and safety equipment.
