BPA is present in some plastics as a monomer, i.e. part of the polymer chain.
The main materials concerned are:
- Polycarbonate: kitchen utensils, childcare items, etc.
- BPA-based epoxy resins: food tins, drinks cans, etc.
Other materials that rarely or never come into contact with food are also concerned:
- Other plastics:
- Polyester carbonate: microwave doors, etc.;
- Polyetherimide: hot drinks machine pumps;
- Polysulfone: filtration membranes for drinking water;
- Polyarylate: water treatment (conduits, pumps);
- Other resins:
- Vinylester resins: shipbuilding, flooring, etc.;
- Phenolic resins: coatings for the construction industry, the transport industry, etc.;
BPA can also be used as an additive in several plastics and resins:
- As a hardening agent in epoxy resins and other resins;
- As a polyamide stabiliser in electro-technical applications;
- As an antioxidant in the rubber used to make tyres, etc.
