Nanu la reng advantage ning bisphenol A epoxy resin?
Bisphenol A bpa ing epoxy resin ing peka-produce ampo peka-magamit a uri ning epoxy resin. Atin yang matas a transparency at me-synthesize ya ibat keng bisphenol A BPA ampo epichlorohydrin keng presensya ning sodium hydroxide. Ing degree ning polymerization, a maki "n", keraklan manibat ya 0 anggang 25. Base keng molecular weight, deng epoxy resins malyari lang i-classify kareng miyayaliwang gradu. Keraklan, deng low molecular weight epoxy resins atin lang average a "n" a mas mababa keng 2 ampo metung a softening point lalam ning 50°C, ampo mayayaus lang soft epoxy resins. Deng medium molecular weight resins atin lang "n" a ulaga pilatan ning 2 ampong 5, a maki softening point a manibat 50°C anggang 95°C. Deng resin a maki "n" a mas maragul kesa 5 (softening point above 100°C) makaclassify la bilang high molecular weight resins.
