Anto ray bentaha na bisphenol A epoxy resin?
Bisphenol A bpa say epoxy resin so sankarakelan ya napapawala tan sankalaknaban ya uusaren ya klase na epoxy resin. Atagey so transparency to tan nanlapud bisphenol A BPA tan epichlorohydrin ya walay sodium hydroxide. Say grado na polymerization, ya tatawagen ya "n", et kaslakan ya manlapud 0 anggad 25. Base ed belat na molekula, saray epoxy resin et nayarin iklasipika ed nanduruman grado. Kaslakan, saray low molecular weight epoxy resins et walaan na average ya "n" ya kulang ed 2 tan say softening point da et abeba nen 50°C, tan tatawagen iratan ya soft epoxy resins. Saray medium molecular weight resins et walay "n" ya balor da ed baetan na 2 anggad 5, ya say softening point da et manlapud 50°C anggad 95°C. Saray resin ya walay "n" ya mas atagey nen say 5 (softening point ya mas atagey nen 100°C) et niklasipika bilang high molecular weight resin.
