I-Bisphenol A (BPA): Ibizo layo lesayensi yi-2,2-bis(4-hydroxyphenyl)propane. Yikristalu emhlophe efana nenaliti enendawo yokuncibilika engu-155-156 °C. Yinto eqakathekileko yokwenza ama-epoxy resins, ama-polysulfone, ama-polycarbonates, neminye imikhiqizo. Ingalungiswa ngokusabela kokuncibilika kwe-phenol ne-acetone ngaphasi kwesenzo se-catalyst.

I-Bisphenol A ifinyelela ukulingana okupheleleko hlangana neendleko nokusebenza – ukukhetha okuhle khulu kokusebenzisa iindleko eziphezulu. Nawufuna ukuthenga imikhiqizo yamakhemikhali ethembekileko, sicela ufune i-Shandong Pulisi Chemical Co., Ltd., edzimelele “emakhemikhali wekhwalithi” begodu sele isebenza iminyaka ema-20.
