Bisphenol A: France Recommends Limits in PolymersPascale Lambert
BPA is a chemical mainly used as a monomer in the manufacturing of polymers, in particular polycarbonate resins, but also epoxy polyester, polysulfone and polyacrylate resins, and flame retardants [11,12,13]. Since the polycarbonate is used for the production of plastic bags, bottles and packagin...
Bisphenol A (BPA)-recognizing imprinted polymers were synthesized using a template immobilized on silica where the template was grafted to aminopropyl silica. The silica-template conjugate was co-polymerized with a cross-linker (ethylene glycol dimethacrylate) and a functional monomer (4-vinylpyridine or...
Bisphenol A (BPA) is used to produce polymers for food contact applications, thus there is potential for oral exposure of humans to trace amounts via the diet. BPA was weakly estrogenic in screening assays measuring uterine weight/response, although much higher oral doses of BPA were required ...

SAO PAULO (ICIS)–Brazilian chemicals producers are lobbying hard for an increase in import tariffs for key polymers and petrochemicals from 12.6% to 20%, and higher in cases, hoping the hike could slow down the influx of cheap imports, which have put them against the w...
In addition, BPA is also used as an additive in other plastics and polymers, particularly as an antioxidant or stabilizer in polyvinyl chloride, printer ink, and in some other products. 9.23 Uses Bisphenol A is used with epichlorhydrin for the synthesis of epoxy resins bisphenol-A type. It ...
Metal food and drink cans are commonly coated with epoxy films made from phenolic polymers produced from bisphenol A (BPA). It is well established that residual BPA monomer migrates into can contents during processing and storage. While a number of studies have reported BPA concentrations in foods...

The safety of most foods, thought to be the primary source of human exposure to BPA, is the responsibility of FDA. Current BPA-containing PC polymers and epoxy resins used in food containers—such as baby bottles and infant formula cans, respectively—are regulated by FDA as food additives, ...
