Bisphenol A (BPA) is a solid material with a faint, medicine-like odour. It is a carbon-based synthetic compound which is miscible with most organic solvents but has poor solubility in water.
BPA is produced in large quantities, primarily for use in the manufacture of tough plastics and epoxy resins, and has been in commercial use since the late 1950s. It is produced by condensing phenol with acetone in the presence of an acid catalyst. Its subsequent reaction with carbonyl chloride produces polycarbonate, which is used to make strong plastics. See Applications for further information.

Applications of Bisphenol A
BPA is a key monomer which is used to make polycarbonate plastics and epoxy resins. Polycarbonate plastic is clear and tough, and as such it is used in a diverse range of common consumer goods such as drinks bottles, sports equipment, CDs and DVDs, impact-resistant safety equipment, medical devices and household electronic goods. It may also be found in some dental devices, sealants and composites, motorcycle helmets, bulletproof windows and heat-resistant plastics such as those used in microwave ovens. Its light weight and clarity also makes it ideal for use in spectacle lenses.
BPA also has several industrial applications, such as in fire retardants, linings for water pipes and in foundry castings. It is further used in a number of chemical processes, among which are the synthesis of polysulfones and polyether ketones, as an antioxidant in plasticizers and as a polymerization inhibitor in the manufacture of PVC.
BPA-based epoxy resins are frequently used as coatings on the inside of food and beverage cans. BPA is also used as a colour developer in thermal paper such as that used in cash registers and credit card terminals.
Storage and Handling
Keep refrigerated and avoid contact with strong oxidizers, strong bases, acid chlorides and acid anhydrides.
The material should be handled in accordance with good industry safety and hygiene practices. Relevant engineering controls should be implemented to control dust levels. Handle with gloves and avoid eye contact and inhalation. Protective clothing may be required depending on recommendations from appropriate risk assessments. Refer to product SDS for further guidance.
